Re: [Haskell-cafe] Comma in the front

Hi

[ a, b, c, ]

I'm surprised this approach isn't more widespread - Are there reasons why haskell syntax could not/should not be defined this way?

I believe GHC allows multiple commas after each other in some places, for example module export lists. Unfortunately the only reason I know this is because it broke code for Hugs. I don't think its technically infeasible to do this, it was just not decided upon at the time. There might be issues with tuples though, for example (1,2,) would be the (,) tuple and not the (,,) tuple, which is a bit weird. Thanks Neil
