type checking for defined types

[mvertes]

The following program sample.go triggers an unexpected result

package main

type ( 
    Number  = int32
    Number2 = Number
)   
    
func f(n Number2) { println(n) }
    
func main() {
    var n Number = 5
    f(n)
}

Expected result

$ go run ./sample.go
5

Got

$ yaegi ./sample.go
run: ./sample.go:12:4: cannot use type main.Number as type main.Number2
