I had not -- because I had no idea such a thing was possible. (So many Perl tricks to learn!) In fact, I still don't know how to find out more about this, because it's impossible to search Perl docs for a "@" and home in on a specific meaning. :-) What's the name of that @{ } construct? This solves my problem perfectly, and has the bonus of not further cluttering the left-hand side of an already complex substitute pattern. Thanks for the new trick!	[reply]

Ah, so it's not really a new operator so much as a novel combination of familiar operators. Anyway, a great tool to have in one's toolbox!	[reply]

What's the name of that @{ } construct? According to perlsecret `@{[ ]}` is the "baby cart" operator.	[reply] [d/l]
