So while I was reading the PyMEL docs today, I came accross the callback function defined in PyMEL by Luma Pictures.

just when I had a look at it i realized it is doing the same thing as partial did! well when Python already had Partial why Luma Pictures would reimplement a function with same functionality and give it a different name, well the Call back does seems logical but then what would be the logic of caling it partial as in functools module ?

Callback vs. Partial ? do they have any advantage over each other , I dont think so!!!
