The (temporary) syntax is
iface seq<T> {
fn len() -> uint;
fn iter(f: block(T));
}
// The 'blah<T>' can be left of to default the name of the
// impl to seq<T>. The 'of seq<T>' can be left off when
// not implementing a named interface.
impl blah<T> of seq<T> for [T] {
fn len() -> uint { vec::len(self) }
fn iter(f: block(T)) { for x in self { f(x); } }
}
Issue #828
This is not a full solution yet. To really get sane error messages,
we'll also have to guess the name to apply to literals, which seems
non-trivial.
I think it should undefined to have multiple modules that link in the same
library, but provide different link arguments. Unfortunately we don't track
link_args by module -- they are just appended as discovered into the crate
store -- but for now, it should be an error to provide link_args on a module
that's already been included (with or without link_args).
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.

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.
Issue #1177
This goes before a snapshot, so that subsequenct patches can make the
transition without breaking the build. Disables kind checking pass, makes
parser accept both new and old-style kind annotation.
Issue #1177
This patch changes how to specify ABI and link name of a native module.
Before:
native "cdecl" mod llvm = "rustllvm" {...}
After:
#[abi = "cdecl"]
#[link_name = "rustllvm"]
native mod llvm {...}
The old optional syntax for ABI and link name is no longer supported.
Fixes issue #547
