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 at puremagic.com
ReportedBy: peng2cheng2 at 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
