Sorry, the match should be $_ =~ /$pat/o, and not against $c, to reduce dupes.

This hardcodes 3 as the context value, if you want better options (for example, if you want to use substrings intsead of regexps for matching, -v, etc.) you probably need more than a single line.

Does someone have such implementation ? Is there a one-liner ("real" one liner) solution ?
