But then you have all these small functions lying around in your module.
If you intend to use them multiple times, then obviously you should
keep them. But if they are intended to be used once, and once only, it
seems bad to leave them there tempting fate.
E.g. you have some code that uses a large lookup table. Rather than type
the lookup table in by hand, you write a function which creates all or
part of it. Once the lookup table is created, you shouldn't use that
function again -- at best it is just sitting around like a third wheel,
at worst it might have side-effects you don't want. So I del the function.
The logic seems impeccable to me, and yet somehow deleting them after they
are used feels ... not so much wrong, as just ... worthy of a
