84c765dbc5 Start building out type propagation framework for inferring expression types in specified contexts. To do this, build a simple expr visitor class.

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.
