f.__qualname__ = "g"
f(a=1, b=0)In CPython:
TypeError: g() got some positional-only arguments passed as keyword arguments: 'a'
In RustPython:
TypeError: f() got some positional-only arguments passed as keyword arguments: 'a'
Example 2
class A:
def f(self, a, /, b=0): pass
A().f(a=1, b=0)In CPython:
TypeError: A.f() got some positional-only arguments passed as keyword arguments: 'a'
