[issue5135] Expose simplegeneric function in functools module

[Ryan Freckleton]

Ryan Freckleton <ryan.freckleton at gmail.com> added the comment:

An elaborate PEP for generic functions already exists, PEP 3124 [
http://www.python.org/dev/peps/pep-3124/]. Also note the reasons for
deferment. I'd be interested in creating a "more limited" generic function
implementation based on this PEP, minus func_code rewriting and the other
fancier items. Sadly I won't have any bandwidth to work on it until January
of next year.

I'd vote for keeping this issue open because of that.

Generic functions are a lesser-known paradigm than OO, and nowhere do common Python documents (including the official docs) try to teach them. That means the first public appearance of generic functions in the stdlib should really be well thought out if we don&#39;t want to encourage poor practices. I agree with Guido that a PEP is required to flesh out all the details.<br>
