          Issue ID: 14905
           Summary: duplicate error message: 'Warning: statement is not
                    reachable'
           Product: D
           Version: D2
          Hardware: x86
                OS: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: timothee.cour2 at gmail.com

dmd -w -c -o- main.d
main.d(3): Warning: statement is not reachable
main.d(3): Warning: statement is not reachable

main.d:
----
bool fun(string s)() {
  return true;
  return false;
}

void main(){
  cast(void)fun!"a";
  cast(void)fun!"b";
}
----

Could we have a global hash of all generated warning/error messages to avoid
repeating them?
(as opposed to a one-off fix to just fix this particular case)
