Rock parses function arguments with default values incorrectly

[marcusnaslund]

All of these should of course be equal, but are unfortunately not:

foo: func (a := false, b := true) // works
moo: func (a: Bool = false, b := true) // works
bar: func (a := false, b: Bool = true) // does not work
car: func (a: Bool = false, b: Bool = true) // does not work

For example, bar fails with error Couldn't unwrap decl 'false: Bool', which suggests rock parses something incorrectly.

Huh, weird.
Will be looking into it.
