Currently list.remove raises ValueError if the element is not in the list.
When called with the count argument, should it raise ValueError if there
are fewer than `count` occurrences of the element in the list?
There's str.replace and str.split that accept a maximum count, and
functions and methods in the re module that accept a maximum count. Is
there any place where such a count isn't treated as a maximum?

I expect some sort of "there's no benefit in this, just write the current

Currently, this is the way to remove `num` occurrences of an element from a
list:
idx = 0
while idx < len(the_list) and num:
if the_list[idx] == element_to_remove:
del the_list[idx]
num -= 1
else:
idx += 1
With a `count` argument to `list.remove`, this is how it would be done:
the_list.remove(element_to_remove, count=num)
(Doesn't necessarily have to be a keyword argument)
Is this a good idea?
Speaking of which, is there a use case for a 'key' argument? Just
wondering...
