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.

4de0b3d947 Allow already bound functions to be bound again.
This commit just disables the check. All of the real work was in previous
commits that moved the target function into the bindings part of the closure
that is tracked by the tydesc.
Closes #754.

9ca0ce91bf Initial implementation of typestate for closures.
There are still things not handled properly: relying on other preconditions
of upvars is likely to cause bad things to happen. We probably want to
disallow it.

b9b674abe7 Start adding support for multiple variable declarations per stmt
This adds parser support and most of the machinery for

    auto x = 10, y = 20;

However, the above still goes wrong somewhere in typestate, causing
the state checker to believe only the last variable in the list is
initialized after the statement.

Tim, if you have a moment, could you go over the changes to the tstate
code in this patch and see where I'm going wrong?

Multi-var-decls without the typestate extension
