I have this enum to get the type of a member field in a struct: enum typeOfMember(T, string member) = typeof(__traits(getMember, T, member));

I'm having problems when I try to used it though. For example:

writeln(typeOfMember!(T, member).stringof); // Doesn't work: Error: initializer must be an expression, not `int[]`

writeln(typeof(__traits(getMember, T, member)).stringof); // Expand the enum, it works.

What is the problem here? I'm using the LDC 1.27.1.

It actually looks like I'm having problems wherever I try to pass that enum as a template parameter.

Thanks! alias typeOfMember(T, string member) = typeof(__traits(getMember, T, member)); works.

But I did not understand what you meant by "enums hold values, not types". Aren't types values at compile time?

Types can be template arguments, if that's what you mean, but they aren't values.
