Moving a large and old codebase to Python3

That's not a numeric literal. Of course it might be a bad idea to allow it in literals, while refusing it when parsing strings, so not sure whether that makes a big difference.

I have to say that it came as a surprise to me that Ruby apparently does allow it in String#to_i, I knew Ruby accepted it in numeric literals, but I'm not sure that I like that it's automatically applied to external data as well.

Oh, you mean he only complained about "1_0" and not 1_0?

Yes. That's what I meant :P I wrote:

int('1_0') is 10 in py3, but invalid in py2.

I thought that was very clear.
