https://github.com/ghc-proposals/ghc-proposals/pull/76#issuecomment-33995299... This appears to have near universal approval. It's certainly a feature I've been grateful for when writing Rust code. I wasn't able to find a thread about this proposal in my email archives, so I apologize if this was redundant. Could this be moved to a decision soon? Thank you, Chris Allen
I am fine with this. Related to our recent discussion: we should probably
require that this be protected by a language extension, like all other
literal notations. Perhaps `UnderscoreLiterals`?

PS: technically, this is not backward compatible :-) Here is an example:
instance Num b => Num (a -> b) where
fromInteger = const . fromInteger
test :: Integer
test = 1_1
where _1 = 2
Currently this evaluates to 1, but with the extension it will evaluate to
11. I don't think that any real code would be affected by this, I just had
a bit of fun writing it.

I have not dug into the details, but the general direction of this proposal looks fine to me.
