You're right. You can use that to, say, do string manipulations based on 
a string array.

However, you cannot use these strings with pragmas or __traits.

I had tried using foreach on __traits(allMembers) in my code, but since 
I went on to do __traits(getVirtualFunctions) using those strings, dmd 
wasn't happy with me. :`(

That's why I use recursive templates in my code.
