ebc61e39d7 Remove temporary fn# syntax 2011-10-20 20:34:04 -07:00
Brian Anderson
5c38f7dfd7 Don't allow fn@ items 
fn@ is intended to be caputring but isn't implemented.

9efdd0f326 Merge ast::proto_shared and ast::proto_closure 
Now they are both just proto_shared and proto_shared takes an
argument indicating that it is sugared as 'lambda'

f324704c0a Parse obj methods as proto_bare 
I don't know if this is the right thing to do, but it works
and it lets 'fn' always mean proto_bare

070c39ca1d Split parsing of fn proto between types, items and anons 
The meaning of various fn incantations is going to get temporarily confusing

0714bb5f7d Fix the problem with check-fast randomly failing 
Trans has been assuming that tag node id's are unique across crates and they
are not so, depending on which way the wind is blowing, it would choose to use
a crate-local tag variant instead of the correct one from std.

No test case since I can't come up with a reliable one that compiles in a
reasonable amount of time.

into the type check

cbe8da0655 make treatment of unchecked/unsafe blocks more uniform 
also repair various errors in the parser related to such blocks.
rename checked_blk to default_blk to reflect the fact that it
inherits its purity from the surrounding context.

9c46cc58cb Add a temporary syntax for bare functions 
Bare functions will be represented as 'fn#' until they're implemented. Then
we'll switch it over to just 'fn'.

33167f7dec Adjust function signatures to allow for vecs being immediate 
Some code was relying on vectors being implicitly by-reference (as
non-immediate value). This adds the necessary &&-sigils.

f26e770745 Make 1-1 parse again 
Issue #954

This is not a very elegant fix -- we should probably do something with
constant folding to handle negative-int alt patterns in the future.

f375391cb6 Patch to error instead of crashing when parsing unmatched double quotes 
Patch to error and fail instead of using all available memory
then crashing to detect the error condition of an unmatched
double quote before the end of a file.

I couldn't get it to show nice error messages, so this may not be
the ideal fix.

A test case for this situation has also been added.

b1bf9ef5ae Break fold's circular reference during unwinding 
This converts the AST fold into a resource that breaks it's own circular
reference (just a temporary workaround until GC), so that failure during fold
will unwind correctly.

d7587c1eda Change convention for specifying referenced argument 
It is now 1-based, rather than 0 based. (Seems more natural, and allows 0 to
be used to refer to self and maybe to closure.)

Also allows non-referenced args to be implicitly copied again.

0b34e0e60b Introduce new semicolon rules 
- Loop bodies and resource constructors aren't allowed to have
  trailing expressions anymore.

- An expression that ends* in a block without trailing expression can
  can not be called, indexed, or subscripted.

- Only expression-statements that end* in a block without trailing
  expression can omit their semicolon.

*) 'Ending in a trailing expression' is defined as being a block or
   construct-ending-in-a-block (if, alt) that either ends in an
   expression itself, or ends in another block-like expression that
   has a trailing expression (by these same rules).
