grinder++ !
It's rather like a solution I came up with, albeit without using the module in question:
my $str = 'f1,f2, SUM(f3),CONCAT(f4,f5, f6), f7';
my ( $tok, @toks, $parens );
while ( $str ) {
my $char = substr $str, 0, 1, '';
$char eq ' ' and next;
$char eq '(' and $parens++;
$char eq ')' and $parens--;
$char eq ',' && ! $parens
and push( @toks, $tok ), $tok = '', next;
$tok .= $char;
push @toks, $tok if ! $str;
}
print join ' -- ', @toks;
...but I didn't want to post it for fear that it wouldn't be very robust. :)

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).
