Very cool! Maybe another idea, instead of lexical, use the rustpython_parser.lexer to lex the float. Then the behavior is the same between floating point literals and the |

Yeah, increasing the binary size would be unfortunate - I'd just like to see the float parsing performance be competitive with |

I would not worry too much about performance right now, but should the behavior be actually the same? Anyways, the work looks good! I will merge it. |
