I wonder if for repr-synonyms, a format specifier to `repr()` could toggle
how the object chooses to display itself would be handy:

x = b'*+-./'
repr(x) # b'*+-./'
repr(x, bytes.REPR_HEX_STRING) # b'\x2a\x2b\x2c\x2d\x2e'
repr(x, bytes.REPR_BYTES) # bytes([42, 43, 44, 45, 46])
repr(x, bytes.REPR_HEX_BYTES) # bytes([0x2A, 0x2B, 0x2C, 0x2D, 0x2E])

Kinda like `format()` but such that all of `eval(repr(x, <whatever>))` are
