Hi all,

Just want to bring up this topic again. From what Robert suggested, the style rule can 
be reduced to the following:

style
     : xpr       		{ $$ = new_style($1, 0); }
     ;
However, this will render the style->and_mask useless as it is never used.
In style expression, '~' and tNOT are treated differently.
'~' is applied as it is parsed, ie from left to right like normal expressions.
However, tNOT is applied at the very end, after all other or_mask are combined and
I believe this is why there are or_mask and and_mask in style.

xpr won't work here as it treats tNOT and '~' the same.

So adding '&' and '~' might be a better solution here.
