Not really no, but I have another idea, assuming the x-modifier is on:
(?x)
(?:
(\()
|(\[)
|(\{)
)
foo
(?:
(?(1)\)
|(?:(?(2)\]
|(?:\}
))))
The idea is to use conditional expressions to check which opening backet
matched and then react accordingly. You'll need to check I've got the ('s
and )'s matching up 'cos I lost count while typing in :-(
HTH, John.
