Oddly, it compiles if you commment out the ; -- the foreach has to be non-empty. Behaviour is quite odd; if there are several items in the tuple, it will work if you don't use the whole tuple; eg Types[0..$-1] and Types[1..$] will work. So it sounds like some kind of memory corruption/unterminated string or similar. Possibly the root cause of some of the bugs in issue 1298. ======== bug.d(9): Error: cannot evaluate foo() at compile time --- int foo(Types...)() { foreach(T; Types) { ; // will compile if you remove this line } return 0; } const int q = foo!("")();
This workaround for this bug has changed. On 1.039, it now fails even if you comment out the marked line. But it compiles if you add [] to the string. int foo(Types...)() { foreach(T; Types) { ; } return 0; } const int q = foo!("abc"[])(); // OK
fixed dmd 1.056 and 2.040
