I'm unsure why the syntax checker is separate from the parser.  Syntax checking
is basically answering the question "can i parse this".

There are semantic checks that we will want to do while parsing:
   the various "features" we track
   variable and function accumulation
   partial AST generation

New things we _must_ be able to do in the new parser:
   strict mode identification needs to be done during the parse stage and
alters the state of the parser to reject constructs that lax mode would allow,
and produces parse time errors instead).  For efficiency reasons this basically
forces us into a recursive-descent parser :-/
