to refrase the question: from within a grammar what is $skip and what
is $Parse::RecDescent::skip?
when you pass Parse::RecDescent a grammar string it does some very
"interesting" things, it creates a new package (this is important),
and bunch of functions in that package and returns an object blessed
into that (dynamically created) package. So, from "within" a grammar
$skip is NOT $Parse::RecDescent::skip because you aren't in the
Parse::RecDescent package. you can do whatever you want to $skip
(which is actually $Parse::RecDescent::00000001::skip or something)
and $Parse::RecDescent::skip won't be affected. anyway, use
$Parse::RecDescent::skip or even better, as Ted Zlatanov mentioned,
the <skip> directive.
hope this helps. if you want details have Parse::RecDescent pre
compile the grmmar and have alook at the file it spits out.
