I would like to loop over an array of names passed to a me(I don't know

I've tried to use a mixin but I can't get the mixin to work on the
string name...

e.g., mixin(alias a = __traits(getAttributes, ~type~););


You need to use a typetuple as well:

import std.typetuple;
enum attribute;

@attribute struct Foo {}

void main ()
{
alias a = TypeTuple!(__traits(getAttributes, mixin(Foo)));
pragma(msg, a);
}
