[Python-ideas] __repr__: to support pprint

[语言破碎处]

Hi, everyone!
Oftenly, __repr__ return "{type}({args}, {kws})"
problem:
    1) to call .format() myself is tedious
        I have seen someone do it wrong: "T(1,)"!
        I write a helper function myself,
            but to import such tiny function everywhere isnot good.
    2) pprint cannot dive into string that from repr()
        To use pprint, I sometimes have to recursively
            turn objects into builtin containers:
            (type_name, args...)

solution:
allow __repr__ to return
    str
    OR tuple: (args, kws)


Better, isn't it?
