Re: Suggestion: Syntactic sugar for Maps!

I am fairly certain someone could write the necessary magic so:

do {'a' ~> 1; 'b' ~> 2}

becomes a map without any changes to the language at all. It seems like throwing syntax at a problem should be a last resort. I often do:

let (*) = (,) in ['a' * 1, 'b' * 2]

I find that quite elegant as an associative list, which you can then convert to a map, a hash table, use as an associative list etc.

I also think that those who are looking for Haskell will have their mind so blown by lazy evaluation that keeping their maps similar isn't so necessary :-)
