in reply to numbered sourcecode listing (oneliners)

I generate my column listings with a very simple one: 
perl -pe 's/^/\t=$.=\t/'

[download]
In emacs, I just hit the tab key for those \t's, or I can type \t instead.

    You can omit the caret in that one too.

      Only if I was golfing and not worried about being clear and working in all circumstances. I never trust the empty match, since it depends on the most recent successful match. True, here, it defaults to an empty string, but why count on that when one single character fixes that problem and communicates the proper intent?

        In Perl "// == /$&/". Is it unintentional or useful feature? I can't imagine any situation when this feature is helpful.

        Because you were in the midst of a golfing match.
