=head1 NAME
Vend::Interpolate -- Interchange tag interpolation routines
=head1 SYNOPSIS
(no external use)
=head1 DESCRIPTION
The Vend::Interpolate contains the majority of the Interchange Tag
Language implementation rouines. Historically, it contained the entire
tag language implementation for MiniVend, accounting for its name.
It contains most of the handler routines pointed to by Vend::Parse, which
accepts the parsing output of Vend::Parser. (Vend::Parser was originally based
on HTML::Parser 1.x).
There are two interpolative parsers in Vend::Interpolate,
iterate_array_list() and iterate_hash_list() -- these routines parse
the lists used in the widely employed [loop ..], [search-region ...],
[item-list], and [query ..] ITL tag constructs.
This module makes heavy use of precompiled regexes. You will notice variables
being used in the regular expression constructs. For example, C<$All> is a
a synonym for C<[\000-\377]*>, C<$Some> is equivalent to C<[\000-\377]*?>, etc.
This is not only for clarity of the regular expression, but for speed.
