[go-nuts] Alternate syntax for Go2 generics and contracts

[Manlio Perillo]

I just read the "official" proposal for Go2 generics and contracts.
The current proposal makes the function syntax more complex, and the syntax 
for the contract is a bit magic.

What about something like:


    type stringer template

    contract (x stringer) {
        var s string = x.String()
    } 

    func Stringify(s []stringer) (ret []string) {
         for _, v := range s {
            ret = append(ret, v.String())
        }
        return ret
    }

instead of


    contract stringer(x T) {
        var s string = x.String()
    }

    func Stringify(type T stringer)(s []T) (ret []string) {
         for _, v := range s {
            ret = append(ret, v.String())
        }
        return ret
    }


Thanks
Manlio
