in thread Idiom for looping thru key/value pairs
The problem with splice is that it would chop the values out of the original array, and he doesn't want to use a dupe.
This might be the time to use old-timey C-style for:
It's ugly, but it avoids the duplication. For the cost of a scalar you could always usemy @list = ('1','val','2','val2','1','val3'); my $self = { _subfields => [@list] }; my @subs; for (my $index = 1; $index < @{$self->{_subfields}}; $index+=2) { push @subs, ${$self->{_subfields}}[$index]; } # waa-la: print $_,"\n" foreach (@subs);
instead.my $aryref = $self->{_subfields};
-- Frag.
