Does anyone know why this code is not working? http://dpaste.dzfl.pl/b89e7b3f
It seems calling "enum a = __traits(getAttributes, Class.member);" is OK without an instance. But if I wrap the __traits call into another template with alias parameter like this: ----------- auto getAttribute(alias target)() { return __traits(getAttributes, target)[0]; } ----------- I can no longer call it at compile time ("enum b = getAttribute!(Class.member)"). What I want to do ultimately is assigning special values to all class members which have a specific UDA while avoiding runtime overhead as much as possible. In pseudo code: ------------ instance i1; static foreach member in i1 static if i1.hasUDA(UdaType) member = specialValue(); ------------ Should compile down to only this: instance i1; i1.member1 = specialValue(); i1.member2 = specialValue(); i1.member3 = specialValue();
