This is not replacable in one line with a def (or without locals()
detritius). Assuming this is good style, it seems odd that
inst.get_foo = lambda: FakeFoo()
is acceptible style, but
get_foo = lambda: FakeFoo()
But surely, none of these are great style, and in fact the lambda
lures you into using it.
I'd propose a far better use is:
inst.get_foo = FakeFoo
or
get_foo = FakeFoo
Sorry, that was a bad example. It is obviously silly if the return
value of the function is callable.
