Try this version of your code that uses Data::Dump and things become obvious:

#! perl -slw use strict; use warnings; use Storable qw(dclone); use Data::Dump qw[ pp ]; my $str = "Rico"; $str =~ m{(?<name>ico)}xms; my $match = dclone \%+; print \%+,; print " match: $match -", pp $match; $str =~ m{(?<buba>R)}xms; my $match2 = dclone \%+; print \%+; print " match: $match ", pp $match; print "match2: $match2 ", pp $match2; __END__ C:\test>816700 HASH(0x22ee20) match: HASH(0x6f218) -{ # tied Tie::Hash::NamedCapture } HASH(0x22ee20) match: HASH(0x6f218) { # tied Tie::Hash::NamedCapture } match2: HASH(0x6f128) { # tied Tie::Hash::NamedCapture }

%+ is not a real hash, but rather a tied hash. And cloning it appears to simply gives you another tied reference to the same global internal data structure.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
