Exactly the opposite! I want to distinguish which branch matched, when the matched strings could all be the same. | [reply] |
With numbered captures, defined( $1 ) tells us if a capture is part of the matching patch.
The equivalent with named captures would be exists( $+{ name } ).
To check which of a set, ( grep exists( $+{ $_ } ), qw( name1 name2 name3 ) )[ 0 ] could be used.
And of course, that simplifies to ( keys( %+ ) )[ 0 ] if only one named capture could have captured.
