Comment:
Replying to [ticket:16505 saraedum]:
> Currently, there is no way to only remove some keys. This is sometimes
necessary if values in the cache are not usable anymore
For this use case, I see no reason to raise `KeyError` when the key does
not exist: I would just ignore non-existing keys.
You should add doctests showing that this also works for a weak cached
function and a cached method (not just plain cached functions).
