This may not be what you want, but starting from Go 1.9 it's possible to
declare a type alias using the syntax
type MyString = string
As opposed to a type definition, an alias declaration doesn't create a new
distinct type different from the type it's created from. Type aliases are
not meant to be an everyday feature of Go, but are intended to be used
during large and complex code refactoring.
