I call this the "Use what you already know" concept. I once saw in a code review a bit of code from someone you didn't trust arrays to know how many elements were in them. It looked a lot like:
my @array = ();
for( my $i = 0; $i < 10; $i++)
push @array, $i;
print "There are $count elements\n";
I've seen the same thing for hashes too, since some people don't read the perlfunc entry for keys().
I'm still waiting to see some Perl code on The Daily WTF?
