1. allow to use '_' in number literals. its used in Ruby and i found that this makes long number literals much more readable. for example

maxint = 2_147_483_648

Sounds like something that can be solved with an infix operator: (~~) :: Integer -> Integer -> Integer a ~~ b = a*1000 + b 2~~147~~483~~648
