https://issues.dlang.org/show_bug.cgi?id=15240 Issue ID: 15240 Summary: errors in isExpression with == not gagged when used in constraint Product: D Version: D2 Hardware: x86_64 OS: Windows Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: r.sagitario gmx.de static if (is(R == what)) pragma(msg, "hi"); property bool isDir(R)(R name) if (is(R == what)) { return true; } property bool isDir(R)(R name) if (!is(R == what)) { return false; } void foo() { isDir!int(0); } The first line with the "static if" does not show an error, while the contraints produce: test.d(5): Error: undefined identifier 'what' test.d(10): Error: undefined identifier 'what' test.d(17): Error: template athis.isDir cannot deduce function from argument types !(int)(int), candidates are: test.d(5): athis.isDir(R)(R name) if (is(R : what)) test.d(10): athis.isDir(R)(R name) if (!is(R : what)) The same happens for ':' instead of '=='. --
