go/types: "const _ string = 1" error message says integers can't be converted to strings #22070
Description
Compiling this package with cmd/compile (or go/types) produces an error message that 1 cannot be "converted" to type string. In fact it can be converted, it just can't be assigned, which is the criteria required here by the language spec.
package p
const _ string = 1
