<em>At that point, i would definetaly try a dispatch table with sub references</em>
<p>I might do something like this:<code>
my $func = ($foo > 7) ?
$bar && \&bar_mysub
|| $baz && \&baz_mysub
: $bar && \&bar_other_mysub
|| $baz && \&baz_other_mysub;
$func->($foo) if $func;
</code>
Update: I admit I might reformat it slightly, but except
for the '?:' operator, its
not any different than the last example in [perlsyn] under
"Basic BLOCKs and Switch Statements". (We do want to
encourage newbies to read the FAQs, right? :-)
<p><strong>Update:</strong> For the curious, here's what [http://perltidy.sourceforge.net/|perltidy] does
with a longer version of the above (the above code
puts makes perltidy put more on one line, so I added
a bit more so it would get more broken up):<code>
my $func = ( $foo > 7 )
? $bar && \&bar_mysub
|| $baz && \&baz_mysub
|| $bam && \&bam_mysub
|| $bak && \&bak_mysub
: $bar && \&bar_other_mysub
|| $baz && \&baz_other_mysub
|| $bam && \&bam_other_mysub
|| $bak && \&bak_other_mysub;
$func->($foo) if $func;
</code>
As always, decide for yourself if this is better or worse,
more or less readable, or more or less readable to
someone else, than whatever else you might come up
with (I actually like [jeffa]'s version below better) :-)
