I thought one could implement something like
class A:
c = 5
d = __thisclass__.c
But apparently this is a *huge* deal. I'm not sure if the reason
it is a huge deal is that it is technically difficult to implement,
or that there is an implicit "lie" in having something (__thisclass__)
standing for something else that doesn't yet exist (and the potential
errors that may arise from this "lie" in sufficiently unfortunate
code). Or maybe something else beyond my noobish ken altogether.
