Hmm, it's literal ' ' (that is, \x20), not whitespace in general,
right? For obligatory whitespace we have \s.
This one has bugged me since the day I first saw it implemented
in PGE. We _already_ have \s, blank,

The verb used doesn't make much sense to me there. I use a rule
when
Including :skip(/someotherrule/). Yes, agreed, it's a huge
improvement. I'd be more comfortable if the default rule to use for
skipping was named skip instead of ws. (On IRC sep was also
proposed, but the connection between :skip and skip is more
immediately obvious.)
Yes, I like skip too.

No. A05 makes it explicit sp is just \x20, and S05 also says that it
matches one space char, which

Yes, the false value is False now, just as the true value is not True.
The reason for changing them is to avoid confusion with the built-in

have a rule or policy that 0-ary functions are generally uppercase,
not just the constant ones.

skip:
- We keep :words as shorthand for :skip(/ws/)
- And :skip is shorthand for :skip(/skip/)
...where skip defaults to ws, but is distinct from it (i.e. it can
be redefined independently).
It also has the benefit that developers redefining skip can call ws
as one

Oh, and since we're calling them regexes, I suggest calling them
regular expressions too, since both regex(p) and regular
