[go-nuts] type parameter names

[Jochen Voss]

Dear all,

I stumbled across a difference between type names and type parameter names 
(in the go1.18 beta): I can re-use a type name as a variable name, but the 
same is not possible with type parameter names.  Is this difference 
intentional?

For illustration, the following code is 
valid https://go.dev/play/p/r2NAddZmoE3 :

    type other int

    func test(x other) other {
            other := x + 1
            return other
    }

But this doesn't work https://go.dev/play/p/Dsh9IgvKDDY?v=gotip :

    type Numeric interface {
            ~int | ~float64
    }

    func test[other Numeric](x other) other {
            other := x + 1
            return other
    }

All the best,
Jochen
