Hi,  ive already started working with the handlers.  I've set up the parser
to accept addition syntax before the ctor.  The type arguments are passed
to a new opcode handler which triggers prior to NEW but after FETCH_CLASS
(if dynamic, after resolve on CONST).

This needs to override the fetching of the class during the current NEW
handler, but to do that I need to supply addition data.

Do you know what I mean?  I'm sorry if I'm explaining it badly.
