Given three objects:

There is another argument, which is that for functions and classes,
the descriptive keyword ("def" or "class") is the first thing you see when
reading the code. For generators, the descriptive keyword ("yield") could
be buried *anywhere* in that block. One can glance at a generator
function and fail to notice that it is a generator function. This is
the one that really bugs me about reuse of "def", although you are
correct that this is a case where practicality has won over purity.
