Normally you don't want literal candidates for basic types (e.g.
"int(0)") since you can type the literal value without the type name.
One exception is if you are creating a named basic type that
implements an interface. For example:
http.Handle("/", http.FileServer(<>))
will now give "http.Dir()" as a candidate since http.Dir is a named
string type that implements the required interface http.FileSystem.
