note tilly It is very much not a good thing, especially when Perl forgets to reinitialize that memory as happens with the infamous <code>my $foo if cond();</code> bug when the condition is false.<p> &lt;gripe&gt;Which would have triggered a warning in Perl 5.10, but p5p in its infinite wisdom decided that there would be too many real bugs reported, and therefore will <b>only</b> report a warning in the case where the author probably intended the odd behaviour.&lt;/gripe&gt; 336822 336867
