Thanks, personally I generally prefer monkeypatching over subclassing.

I mentioned it tho, because people kept criticizing me for that.

In my experience is subclassing only a good way, if the original author supported it from the beginning.

Monkeypatching is closer to the metal, and it's clear why it fails if it fails.

Exception here: I doubt monkeypatching is threadsafe, but I never tried.
