But, but, but [Skip gets momentarily apoplectic, then recovers...]
"operator.identity" is way more to type than "lambda x: x". Plus you have
to remember to import the operator module. <0.5 wink>
Not to mention which (from "pydoc operator"):
[The operator module] exports a set of functions implemented in C
corresponding to the intrinsic operators of Python.
Last time I checked, Python didn't have an intrinsic "identity" operator.
For which reason, I'd be -1 on the idea of an identity function, certainly
in the operator module.
