Ouch. # won't work for that (in SA at least) as it comments out the
rest of the RE.
Ack! Forgot about that minor difference with SA. # is my general go-to
character for that in normal Perl scripts.
This should illustrate the same point with the minor improvement of
actually *working* in SA:
m^http://match/this/url/^
I tend to avoid using symbols that are syntactically significant in REs
for that purpose. In your example, you can't then anchor the RE at the
beginning of the URL because ^ has been repurposed as the RE delimiter.
--As for the rest, it is mine.
Since we've already established this is Perl...
I like to use braces. Perl handles them (and brackets or parens)
specially: Open with the opening brace and you close with the closing
brace. I think Perl will parse for balance as well, but I haven't checked
at the moment.
m{http://match/this/url}
In general though I do tend to stick with slashes unless it's going to be a
problem; it's just more common and easier for people to recognize.
