Traits in a template enum

[Some Guy via Digitalmars-d-learn]

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:
```D
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.
