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.

b927b55863 Finally get around to allowing *use* of a named incoming function argument. The first step is to set up a scope for them and walk the argument names, keeping track of access path 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.

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.

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)))

2bafb0e8fb Introduce new NamedDecl and FuncDecl classes. The difference between the two is syntactic sugar, so most clients want NamedDecl. This doesn't implement FuncDecl yet, which isn't a high prio for me in the short term.
