cfa09d35a3 Revert "allow fn exprs to omit arg types" 
This reverts commit 1ba4ca4c4a.
 2012-05-03 14:42:34 -07:00
Niko Matsakis
1ba4ca4c4a allow fn exprs to omit arg types 
also, avoid using type variables for fn args with omitted types
unless necessary.  This will be important for bound regions in
fn types.

fixes #2093

825fd1808e lots of work to make iface/impls parameterized by regions 
- paths can now take region parameters, replacing the dirty hack
  I was doing before of abusing vstores.  vstores are now a bit
  of a hack though.

- fix various small bugs:
  - we never checked that iface types were compatible when casting
    to an iface with `as`
  - we allowed nonsense like int<int>
  - and more! (actually that may be it)

734166f41c Print out return type correctly in typestate error message 
In the "not all paths return" error message, typestate was printing
the AST type from the fn decl, not the ty::t type. This ended in tears
when the AST return type was "ty_infer". Now it looks up the function node
ID's type and uses util::ppaux::ty_to_str instead.

Closes #2163.

5c12cd72f4 Allow classes to implement ifaces 
Introduce syntax like:

iface animal { ... }
class cat implements animal { ... }

to allow classes to implement ifaces. Casting classes to ifaces
is *not* yet supported. ifaces that a class implements are not
yet included in metadata.

The syntax is subject to change, and may go away completely if we
decide to use duck typing to relate classes with ifaces (see
http://smallcultfollowing.com/babysteps/blog/2012/04/10/declared-vs-duckish-typing/ )

c0d61795de wip: refactor repr of regions 
- we now distinguish bound/free parameters (see region-param

- we also track bounds on region variables
- also, restructure fold_ty() to have multiple variants without
  duplication instead of one overloaded folder.  This also allows
  for using block functions.

commit, this syntax will be required. For now, you can write either
self.f() or f().

I added a "privacy" field to all methods (whether class methods or not),
which allowed me to refactor the AST somewhat (getting rid of the
class_item type; now there's just class_member).

Now that core exports "option" as a synonym for option::t, search-and-

The only place that still refers to option::t are the modules in libcore
that use option, because fixing this requires a new snapshot

Marijn Haverbeke
87b064b249 First stab at operator overloading 
When no built-in interpretation is found for one of the operators
mentioned below, the typechecker will try to turn it into a method
call with the name written next to it. For binary operators, the
method will be called on the LHS with the RHS as only parameter.

Binary:

    +   op_add
    -   op_sub
    *   op_mul
    /   op_div
    %   op_rem
    &   op_and
    |   op_or
    ^   op_xor
    <<  op_shift_left
    >>  op_shift_right
    >>> op_ashift_right

Unary:

    -   op_neg
    !   op_not

Overloading of the indexing ([]) operator isn't finished yet.

9dc59e1506 Export all enum variants by default; new syntax for selectively exporting variants 
See issue 1426 for details. Now, the semantics of "export t;" where t is a tag are
to export all of t's variants as well. "export t{};" exports t but not its
variants, while "export t{a, b, c};" exports only variants a, b, c of t.

To do:
- documentation
- there's currently no checking that a, b, c are actually variants of t in the
 above example
- there's also no checking that t is an enum type, in the second two examples above
- change the modules listed in issue 1426 that should have the old export
semantics to use the t{} syntax

I deleted the test export-no-tag-variants since we're doing the opposite now,
and other tests cover the same behavior.

e36df0f6c8 Handle fail after return correctly in typestate 
Previously, typestate would conclude that this function was

i_diverge and i_return bits correctly in the fail case. Fixed it.

7c7559edaf Disallow variable names that shadow tags in scope 
Now, if you have a tag named "foo", a variable declaration like
"let foo..." is illegal. This change makes it possible to eliminate
the '.' after a nullary tag pattern in an alt (but I'll be doing
that in a future commit) -- as now it's always obvious whether a
name refers to a tag or a new declared variable.

resolve implements this change -- all the other changes are just to
get rid of existing code that declares variables that shadow tag
names.

I think it should undefined to have multiple modules that link in the same

link_args by module -- they are just appended as discovered into the crate
