           Summary: Never referenced local variable compiles without
                    error.
           Product: D
           Version: 2.029
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P2
         Component: DMD
        AssignedTo: nobody@puremagic.com
        ReportedBy: peng2cheng2@yahoo.com


Per Paragraph 2, "Local Variables" in "Functions" DMD 2.0, it is an error to declare a local variable that is never referred to. But this compiles and runs fine:

--- code

import std.stdio;

void main(){
    int i = 10; //never referred to -- should be error ?
    int k;
    writefln("%d", i + 3);
}

--- terminal

ex$> /opt/dmd2/linux/bin/dmd2
