We should probalby warn when defining a method foo on {foo: int} etc.
This should reduce the amount of useless typevars that are allocated.
Issue #1227
Move the name of the bundle to the front, allow type parameters (not
handled yet), and add a 'for' keyword:
impl utils for int {
fn str() -> str { int::str(self) }
fn times(f: block()) { ... }
}
See src/test/run-pass/nested-patterns.rs for some examples. The syntax is
boundvar@subpattern
Which will match the subpattern as usual, but also bind boundvar to the
whole matched value.
Closes#838
Also shuffles around the organization of numeric literals and types,
separating by int/uint/float instead of machine-vs-non-machine types.
This simplifies some code.
Closes#974Closes#1252
LLVM code generator emits the ".file filename" directive for ELF
backends. Value of the "filename" is set as the LLVM module identifier.
Due to a LLVM MC bug[1], LLVM crashes if the module identifer is same as
other symbols such as a function name in the module.
This patch adds a ".rc" suffix (means crates) to LLVM module identifier
to workaround the bug.
Fixes issue #1251.

The path information was an optional "filename" component of crate
directive AST. It is now replaced by an attribute with metadata named
"path".
With this commit, a directive
mod foo = "foo.rs";
should be written as:
#[path = "foo.rs"]
mod foo;
Closes issue #906.
It's proving too inflexible, so I'm ripping out the extra complexity
in the hope that regions will, at some point, provide something
similar.
Closes#918
This involved adding 'copy' to more generics than I hoped, but an
experiment with making it implicit showed that that way lies madness --
unless enforced, you will not remember to mark functions that don't
copy as not requiring copyable kind.
Issue #1177
This is intended to solve the problem of how to pass arguments to
constructor functions -- you want to move in rvalues, but not have to
explicitly copy stuff that is not an rvalue. The by-copy passing
convention will ensure the callee gets its own copy of the value. For
rvalues, it'll just pass off the value. For lvalues, it'll make a
copy.
