repeated _ parameters¶

basedpython lets _ appear more than once in a function or lambda signature. python rejects this as a duplicate-parameter error; basedpython only exempts _ (the unused-argument convention), so signatures that ignore several arguments don't need invented placeholders:

def f(_, _):
    print(_)

g = lambda _, _: 1

references to _ in the body resolve to the first parameter. duplicates of any other name remain a syntax error
