This is a bug report for perl from cpan@goess.org,
generated with the help of perlbug 1.40 running under perl 5.25.5.


-----------------------------------------------------------------
[Please describe your issue here]

I'm suggesting a documentation change. perlrecharclass says "Most characters
that are meta characters in regular expressions...lose their special meaning
and can be used inside a character class without the need to escape them" and
goes on to list the ones that do need to be escaped. It does *not* list a '$'.
But this will not match a dollar sign or a comma:

  [$,]

and it would be good advice to point out that a '$' is as special inside a
character class as it is anywhere else in a regular expression.


[Please do not change anything below this line]
