I am not sure I understand your question because it already omits an=20
error. If you're asking how to get that code do what I think you want,=20
then the 'is' expression can be used with 'static if' to include the=20
comparison into the program only for string types:

import std.typecons;
import std.stdio;

void main() {
   foreach(i; tuple(10, "lemon", false, "John", 1.6, 'c')) {
     writeln(i);
     static if (is (typeof(i) =3D=3D string)) {
       if(i =3D=3D "John") break;
     }
   }
}
