http://d.puremagic.com/issues/show_bug.cgi?id=10532 Summary: Silence some unreachable statement warnings when in a static foreach Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody@puremagic.com ReportedBy: andrej.mitrovich@gmail.com --- Comment #0 from Andrej Mitrovic <andrej.mitrovich@gmail.com> 2013-07-03 18:34:26 PDT --- ----- import std.traits; enum E { a, b} void main() { foreach (e; EnumMembers!E) { if (e == E.a) continue; // lots of code follows.. auto x = 1; } } ----- $ dmd -w test.d > test.d(14): Warning: statement is not reachable I don't know if this is doable, but it's a little annoying that we have these unreachable statement warnings when in a static foreach loop. It forces use to use an else statement, but this introduces indentation. In this specific test-case the alternative could be to Filter!() through the EnumMembers so "E.a" never appears in the loop, but for more complex cases such filtering may not be usable. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
