sys._getframe() has to create frame objects, which is relatively expensive. Usually the calling function object should be enough.

> Usually the calling function object should be enough.

I want to at least provide some historical context on why sys._getframe() exists.  I originally wrote that to support PEP 292 and internationalization in Mailman.  This has since been extracted into the flufl.i18n package.  Here is the use of sys._getframe() in that library:

You can see that the reason this exists is to dig out the local and globals of the context in which the _() function is invoked.  This greatly reduces the need to repeat yourself in i18n call sites.

I'm not saying sys._getfunc() is or isn't useful, but it won't change original need for sys._getframe().
