I would think that my_ws would be a rule of some sort:
rule my_ws { [ \s+ | \< /? b \> ]* }
Also, it wasn't noted in the previous post, but one can
explicitly call the "default" ws rule by referring to it explicitly,
as in <Rule::ws>. (Currently PGE has it as <PGE::Rule::ws>.)
So, presumably one could do
rule Month :w(&my_ws) { J a n # my_ws rule here
[:w(&Rule::ws) . . . ] # "default" ws rule here
[:w(0) . . . ] # no :w here
PGE doesn't yet implement rule arguments to the :w modifier, but
I bet we can add it without too much trouble. :-)
