That silently ignores whitespace (read up on <skip>).
Also, P::RD is rather slow. I'd even say inexcusably slow if you're just using it as a tokenizer. May I suggest a much faster tokenizer?
use strict;
use warnings;
sub process_token {
my ($token) = @_;
print("Token: $token\n");
}
{
my $str = "ABC[GHI]XY[Z]1A";
for ($str) {
/\G \[ ([A-Z]*) \] /xgcs && do {
process_token("$1");
redo
};
/\G ([A-Z]) /xgcs && do {
process_token("$1");
redo
};
/\G (.) /xgcs && do {
printf("Unexpected '%s' at pos %d\n", $1, pos()-length($1));
redo
};
}
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
