Here group is defined as a value (that happens to be a function) since syntactically "let group = ..." is a value definition because there are no syntactic arguments after 'group'. Values cannot be generic. You need to define group as a syntactic function with arguments after 'group'. Functions can be generic (obviously).

let group xs = Seq.groupBy (fun a -> a) xs

let group = Seq.groupBy<'T,'T> (fun a -> a )
let letters = seq['a';'b';'c';'a';'b';'r';'c';'t';'q';'a']
let numbers = seq[5;2;3;2;3;4;5;1];
let n = group numbers//constrains group to int
let s = group letters// group by wont work here
In VS 2010 the above code gives me trouble.
Why is 'T constrained to be only int
Any help/pointers in generics would be great.
