That is, the range operation is evaluated, and all members of the range are... (3 Replies)

tie::hash::namedcapture
Tie::Hash::NamedCapture(3pm) Perl Programmers Reference Guide Tie::Hash::NamedCapture(3pm)NAME
Tie::Hash::NamedCapture - Named regexp capture buffers
SYNOPSIS
tie my %hash, "Tie::Hash::NamedCapture";
# %hash now behaves like %+
tie my %hash, "Tie::Hash::NamedCapture", all => 1;
# %hash now access buffers from regexp in $qr like %-
DESCRIPTION
This module is used to implement the special hashes "%+" and "%-", but it can be used to tie other variables as you choose.
When the "all" parameter is provided, then the tied hash elements will be array refs listing the contents of each capture buffer whose name
is the same as the associated hash key. If none of these buffers were involved in the match, the contents of that array ref will be as many
"undef" values as there are capture buffers with that name. In other words, the tied hash will behave as "%-".
When the "all" parameter is omitted or false, then the tied hash elements will be the contents of the leftmost defined buffer with the name
of the associated hash key. In other words, the tied hash will behave as "%+".
The keys of "%-"-like hashes correspond to all buffer names found in the regular expression; the keys of "%+"-like hashes list only the
names of buffers that have captured (and that are thus associated to defined values).
