Subject: Pattern with \# and /x leads to error Invalid regex: /x

From: Andreas Guldstrand <andreas.guldstrand@gmail.com>
When you give `rxrx` a pattern that has an escaped # and try to supply the /x flag, you get an error message saying: regex: /Invalid regex: /x Try with input: / \# /x This obviously should parse properly, but even so, "/x" is in fact a valid regex since you don't need the closing "/" in `rxrx`.

Hi Andreas,

Thanks for the report.

The error only occurs in Perl 5.18 and later.
It is caused by changes in the way Perl parses regexes
from 5.18 onwards. It is not clear that there is any way
I can work around this behaviour.

I will continue to work on the problem, however.

Sorry not to be able to solve it immediately,

Damian
