http://d.puremagic.com/issues/show_bug.cgi?id=10179 Summary: Tuple assignment should not cause "has no effect" error even if the length is zero Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: k.hara.pg gmail.com Currently zero-length tuple assignment would cause "has no effect" error. struct S {} void main() { S s; static assert(s.tupleof.length == 0); s.tupleof = s.tupleof; // error } This is basically not bad, but in generic code this behavior requires additional length check. struct S(Types...) { Types field; void set(S rhs) { //field = rhs.field; // --> When Types.length == 0, "has no effect" error occurs. // Workaround static if (Types.length > 0) // additional check field = rhs.field; } } void main() { S!(int, long) s1; s1.set(s1); S!() s2; s2.set(s2); } So I think that stop reporting "has no effect" error for tuple assignment is small but useful improvement. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
