Try the patch, you can make changes (for those that aren't aware) 
by changing the token in Grammar/Grammar to whatever you wish. It is easy
to do and you need only recompile after this step. 

example:

    assexp: xor_expr ['->' xor_expr] 

could become

    assexp: xor_expr ['magic' xor_expr]


    >>> 'hello' magic words
    'hello'
    >>> words
    'hello'


Note that Mr Barnett may need to look at other fixes to get
his '~=' idea off the ground (tokenizer.c and specifically adding a new
token)

I've recommended that we close this issue.

Cheers,
