https://issues.dlang.org/show_bug.cgi?id=22872 Issue ID: 22872 Summary: __FUNCTION__ with opApply gives name of generated delegate instead of enclosing function Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: snarwin+bugzilla gmail.com As of DMD 2.099.0, the following program fails to compile: --- module example; struct HasOpApply { int opApply(int delegate(int) dg) { if (int result = dg(0)) return result; return 0; } } void main() { foreach (x; 0 .. 1) { // ok static assert(__FUNCTION__ == "example.main"); } foreach (x; HasOpApply()) { // error static assert(__FUNCTION__ == "example.main"); } } --- The error is: --- example.d(23): Error: static assert: `"example.main.__foreachbody4" == "example.main"` is false --- This happens because __FUNCTION__ is evaluated after the compiler has transformed the foreach loop into a call to HasOpApply.opApply. --
