I think you've fallen straight into a typical anti-pattern: modifying
a component just because you have source.  You'll pay for the
mistake many times over, even if it's a small mod, like here.

Inherit from the class, override its method, and you have no
need for such changes, while achieving the same effect. *MUCH*
better.
