Mel/Python: Splitting a string by a string (tokenize vs .split)

I know its only a small post and I don't go into detail, more of an outline... it really did bug me was how there are no expressions for tokenize.
I spent a bit of time trying to split a string (ie "L_clavicle_bind_jnt") by with the string "_bind_".
What I found with using tokenize was that it will split the string by the characters instead of the entire string, which to me, was a pain in the backside as I wanted {"L_clavicle","jnt"} but what i'd get with tokenize was {"L,"clav","cle","j","t"}. Now this wouldn't do, and I could find any out of the box way of doing this (I wanted to replace "_bind_" with "_IK_", etc to search), so I ended up turning to python (yet again).
It couldn't be simplier.
Which translated as -
python("'"+$child+"'.split('_"+$namespace+"_')") ;
Thinking about it now, im sure there is a command to do this in mel, I just cant find it...
