Check "man perlre". It seems it would match beginning or end of expressio=
n=20
[^$] and "word boundaries", which usually means the position between alnu=
m=20
and non-alnum chars.

I usually avoid using those "backslashed shortcuts" in writing regexps, a=
s I=20
find that it makes them harder to read and understand...
