[Haskell-beginners] Possible to update Haskell syntax

I'm very interested in learning Haskell, but one frustration is that lists always require commas. As an example [1,2,3,4] is a valid expression, but [1 2 3 4] is not. In this ideal world, another example would be that [(fun1 3 4) 7] would be a valid expression and be a two-element list equivalent to [fun1 3 4, 7]. If what I am suggesting is syntactically possible and doesn't break more advanced features of the language that I (as a beginner) am unaware of, I'm interested in patching the open source for my own use (as well as others who might want it).
