The problem is that using my $a and my $b will prevent the built-in $a and $b
from being used and as a result is a bad idea. We should make sure that
synopses and other code excerpts in the documentation of Perl modules reflect
the Perl best practices, because less clueful people may be tempted to duplicate
them in their own code. And then they go to online forums and ask us why their
code is broken.
So the lexical "$a" and "$b" here should be replaced with something less
dangerous.

Well, I hope I didn't also make the same mistake (again).
