This is not a bike-shedding mail per se, but an inquery into a bike-
shedding.

The P0288 any_invocable proposal [1] has cause some naming discussions,
such as P2265, which is tracked at [2].

There were originally two proposals, both of which called it
unique_function, but some are strongly against that name. My question
is, what are the arguments against the unique_function name?
