Per https://bugs.python.org/msg394731 suggestion. For instance, mpq_set_str() does support this. Also, gmpy2.mpq(). Tentative patch attached. |

Of course, I'm for it. But we have to be consistent... I was surprised to realize `complex` doesn't accept '2 + 3j' (even though it accepts '(2+3j)', and even '\n2+3j\t'). There are a lot of slippery slopes here (e.g. how about 3_j?). I think that once we allowed _ in integer literals, suddenly we could add more separation between digits than around them in many contexts, and that just seems wrong. |

The PEP 515 added '_' as a separator between digits. But the imaginary unit is not a digit. For same reason '1_/_2' shouldn't be allowed for the Rational constructor. (Unfortunately, the Decimal class breaks this PEP convention as well as some other, see issue44267. For example, it accepts things like '1_._2'.) |
