Show HN: Forge – a library for dynaimcally revising function signatures

With forge, you can add, delete, or modify individual parameters as well as convert argument values or validate them.

    import forge
    
    def sumthree(a, b, c):
        return a + b + c
    
    @forge.compose(
        forge.copy(sumthree),
        forge.modify('c', default=3),
    )
    def sumthree_default(**kwargs):
        return forge.callwith(sumthree, kwargs)
    
    assert forge.repr_callable(sumthree_default) == \
           'sumthree_default(a, b, c=3)'
    
    assert sumthree(1, 2, 3) == \
           sumthree_default(1, 2) == \
           (1 + 2 + 3)
    

Today a major revision (v18.6.0) was released.
