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.

d5f834512e Next step to allow use of named arguments: Create a new ArgDecl AST node, and have SemaDecl form them. We now correctly diagnose argument name redefinitions (though the diagnostic sucks because we don't have loc info)

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.

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.

b3c9942644 Rework handling of sequence expressions and juxtaposition to eagerly bind arguments to functions. This means that in situations like: 
foo (_0)  bar (_0)

that _0 will be bound properly and individually to foo and bar when they are functions, but if they aren't, then this is just one big 4-element sequence.

ba04392294 Tighten up sema of anon closure arguments to reject invalid code like this: 
func funcdecl6(a : int, b : int) -> (int,int) -> int = _0+_1;
var funcdecl7 : (int,int)->(int,int)->int = _0+_1;

It's not valid to bind anon closure arguments to functions, use named arguments instead.

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)))
