<blockquote><em>If not, why not? What do you use instead?

<p>
It's just a matter of taste. I'm not <em>against</em> using <code>not</code>, I just don't happen to prefer it.
<p>
You give the following example:
<p>
<code>
print "$pattern not found in $file\n" if not $found;
</code>
<p>
In this case I would use unless:
<p>
<code>
print "$pattern not found in $file\n" unless $found;
</code>
<p>
As for <code>if (not -r $file) {...}</code>, I typically use the bang operator (!) rather than <code>not</code> -- just a matter of preference, probably due to my C influences.
