<p>It is also legal to use a number or another variable wherever you might use a regex:
<code>
$s = '0123456789';;
print $s =~ 0;;
1
$r = 123;;
print $s =~ $r;;
1
</code>
<p>Whatever you put there, perl will try to resolve as a regex.
<P>The downside is that you can't use modifiers without // or m//.
