New submission from NODA, Kai <[email protected]>:
class X:
def __bool__(self):
return True
x = [1, 2, 3]
x.sort(reverse=X())
print(x)
print(sorted([1, 2, 3], reverse=X()))
TypeError: an integer is required (got type X)
We can always still do
x.sort(reverse=bool(X()))
print(sorted([1, 2, 3], reverse=bool(X())))
but that isn't cool
