a885cd5dc5 Diagnose completely unresolved expressions with an error like this:
data.swift:114:10: error: ambiguous expression could not resolve a concrete type
var xx = :Zero;
         ^

Do this with a very general pre/post-order walking function.

ad438c55e3 Implement the rest of sema for scoped identifier references (X::Y) we now get a proper DeclRefExpr, and this:
var def = DataSearchFlags::None;

-ast-dump's into:

(vardecl 'def' type='DataSearchFlags'
 (declref_expr type='DataSearchFlags' decl=None))

ac855b690b Move ActOnTypeAlias to SemaDecl since a type alias *is* a decl that *installs* a type. Add some fixme's and rename some junk in ASTContext relating to the typemap. Diagnose redefinitions of named types. Install a typemap entry when a data declaration is defined.
We can now declare variables to be of data type.

d2abfde434 introduce a new builtin type to represent the result of the else binary operator (which is a temporary hack until we get user defined types).
Use it to define ife/else.  Fix some precedence/parsing bugs that implementing else exposed.

f704c58c42 Two significant changes:
1. Change the representation of TupleType to contain TupleTypeElt structs instead of PointerUnion<Type*, NameDecl*>
 2. Change type canonicalization to not strip field names off tuples, and change type conversion logic to use canonical types again.

Also adds some stuff to the todo list, destined to never be short.

04f7a08621 add support for tuple field access with ".", e.g.:
var a : (int, var f : int, int);
  var b = a.field0+a.field1+a.f;

This also eliminates TupleConvertExpr.

1bb344c282 strength reduce our handling of dependent types. Now, you can't compose dependent types, there isn't a (dep, int) type, the whole tuple gets dependent type. This simplifies things a bit.

7a5b428772 start reworking tuple compatibility: two different tuples aren't compatible because their canonical type is the same, they are compatible because one can be converted to the other. I'm just going to rip out canonical type support for now.

667078650a Implement support for anonymous closure arguments. For example, we can now compile this:
var func6 : ((int,int) -> int) -> ();  // Takes a function, returns nothing.
func funcdecl5() {
  func6(_0 + _1);         // Closure with two named anonymous arguments
}
into:

  (apply_expr type='()'
    (declref_expr type='(int, int) -> int -> ()' decl=func6)
    (closure_expr type='(int, int) -> int'
     (anondecl '_0' type='int')
     (anondecl '_1' type='int')
     (tuple_expr type='int'
      (binary_expr '+' type='int'
       (declref_expr type='int' decl=_0)
       (declref_expr type='int' decl=_1))))))))

However, there are still some problems with this (and we're definitely not doing type inference yet, all anon args are assumed 'int').

874421d4ce Implement AST and Sema support for auto-closures. We now parse:
var closure1 : () -> int = 4;  // Function producing 4 whenever it is called.
var closure2 : (int,int) -> int = 4; // Has some (dead) arguments.

into:

(vardecl 'closure1' type='() -> int'
 (closure_expr type='() -> int'
  (integer_literal type='int' value=4)))
(vardecl 'closure2' type='(int, int) -> int'
 (closure_expr type='(int, int) -> int'
  (integer_literal type='int' value=4)))
