Re: [Haskell-cafe] IO () and IO [()]

I don't think writing (1,) is an option for Haskell, it looks like a section (and should be one). On Wed, Mar 12, 2008 at 9:13 PM, Bryan O'Sullivan wrote:

Yes, I wish Haskell had a 1-tuple. The obvious syntax is already taken, but I could accept something different, like 'One a'.

Python's one-tuple syntax is (1,). The obvious difficulty with adapting this notation to Haskell lies in how one might write the constructor as a section.
