I totally support this proposal.   I've definitely wasted time in the
past trying to invent my own workarounds for the use cases you
describe.

Obviously, there will be some bikeshed debates on __this__ vs.
__name__ vs. __func__, etc.  I don't have an opinion there, just want
*something* handy for introspection, DRYness, etc.

A more interesting question is whether __this__ would just always be
there (that's my vote), or if you should have to apply a special
decorator to get it (which I oppose, but I can see some merits).
