Actually form ApplyExprs.  We're not checking that the actual argument matches the formal argument for a function yet, but we can parse some nice stuff like:

var func3 : () -> () -> ();     // Takes nothing, returns a function.
var call4 = func3()();

into:
(vardecl 'call4' type='()'
 (brace_expr type='()'
  (apply_expr type='()'
   (apply_expr type='() -> ()'
    (declref_expr type='() -> () -> ()' decl=func3)
    (tuple_expr type='()'))
   (tuple_expr type='()'))))
