985c32ef4c Partially implement destructuring locals 
You can now say

    let {bcx, val} = some_result_returner();

Similar for loop variables. Assigning to such variables is not safe
yet. Function arguments also remain a TODO.

3e63fdc4c9 Thread kinds into the type system. Don't quite activate yet, since it breaks stdlib and snapshot isn't ready to compile modified stdlib. 2011-07-28 13:29:39 -07:00

a11bb404a5 Further refinement to kind system lattice and type-kind rules; first successful caught kind error (prohibits copying a pinned resource, though trans already caught it later). 2011-07-27 21:23:54 -07:00

d1298f768c Have bind support non-alias parametric non-bound arguments. 
This was previously disallowed by the typechecker and not properly handled
in trans. I removed the typechecker check (replacing it with a simpler
check that spawned functions don't have type params) and fixed trans.
Closes #756.

f8bb5a3b58 Make ty::ctxt be boxed. 
Arguably we should leave ty_ctxt as a bare rec and just always work with
boxes of it. This winds up being simpler and prettier, though.

bd4aeef78b Beginnings of support for constrained types 
Programs with constrained types now parse and typecheck, but
typestate doesn't check them specially, so the one relevant test
case so far is XFAILed.

Also rewrote all of the constraint-related data structures in the
process (again), for some reason. I got rid of a superfluous
data structure in the context that was mapping front-end constraints
to resolved constraints, instead handling constraints in the same
way in which everything else gets resolved.

eeda0f4ab1 Don't unbox types in ty::is_binopable, do it on typeck side instead 
Closes issue #631

Removes ty::strip_boxes entirely, since unboxing is now more complicated
anyway.
