Hello,
I am not hearing any objections about this, so I am going to mark it as
accepted.

I’m ok with this, although I have not thought deeply about the details.

Hello,
This e-mail is about pull request #76, to allow underscores in numeric literals:
https://github.com/takenobu-hs/ghc-proposals/blob/numeric-underscores/propos... https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Ftakenobu-hs%2Fghc-proposals%2Fblob%2Fnumeric-underscores%2Fproposals%2F0000-numeric-underscores.rst&data=02%7C01%7Csimonpj%40microsoft.com%7C43f4d68308cc457345c608d5260b15d4%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636456751412020624&sdata=NJviNm0jzZTC5BXIPylzb2WsWtJRJk%2B2upa8ImD%2F6y0%3D&reserved=0
In short, this is a very simply feature, which modifies the notation for numeric literals to allow writing underscores (_) in the middle of literals. The underscores are only to increase readability, and have no effect on the meaning of the program. So, for example, I could write things like: 10_000_072 or 0xFFFF_FA10.
Many other languages have a similar feature (especially hardware specification languages) and I see no downsides to it, so I think we should accept it.
Please respond to this e-mail if you have objections.
Cheers,
