Esteemed fellow monks,

Reviewing some of my Perl code, it just occured to me that I could "optimize" this expression:

join '', $config{'prefix'}, $item, $config{'suffix'}
...into something shorter, like this:
join $item, @config{'prefix', 'suffix'}

I still prefer the first version, however, as the second one tends to obfuscate the order of parts in the final result. It could inconvenience extension, too.

Of course, simple concatenation would be even more straightforward:

$config{'prefix'} . $item . $config{'suffix'}
But I have no strong opinion there, since the join-tightly idiom seems commonplace enough to be recognized as equivalent. What do you think?
