OK -- thanks. I'd seen that before, but thought it was a
different syntax [[]]. It's still the character class
syntax [], but with something "weird" in it [:digit:].
Makes sense now.
It all depends on where you've been, I guess. I came from
Korn shell land where there were three ways to spell "test".
test args
[ args ]
[[ args ]]
Yes, the "[[" and "]]" were two-character operators. The
doubles were introduced in a later version and have a much
richer (super)set of operators than the single-character
operators. I "parsed" the Perl [[:digit]] similarly.
Now it makes sense. I can remove my "special case" rule --
it's cosistent with what I already knew.
Thanks again.
