94110869e0 add support for parsing attribute lists, and add the first attribute, infix=42. It is now parsed and slammed into the AST, but not used.

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.

9a0d6c735a change the handling of nullable so that hte parser actually checks for the error and only invokes sema if the inputs are valid, tidying up some code.

other values.  crazzay.

7ff4cc6e21 split the decl processing stuff in Sema out into a new 
SemaDecl class where it belongs.  Tidy up headers a bit.

be a keyword

f7c8e53359 implement isa/dyncast and dumping support for exprs. 
We can now parse and print this:
var x3 = 4+5*4+12/97;

into:
(vardecl 'x3'
 (binary_expr
  (binary_expr
   (integer_literal 4)
   (binary_expr
    (integer_literal 5)
    (integer_literal 4)))
  (binary_expr
   (integer_literal 12)
   (integer_literal 97))))

5450892284 Set up trivial parser support stuff and sketch out a few 
productions.  We can now get this far:

simple.swift:4:5: error: expected a top level declaration
var x : int;
    ^
simple.swift:5:5: error: expected a top level declaration
var x2 = 4;
    ^

Yay for amazing error recovery!
