Pass symbol to template?

[JS]

I have some templates to help initialize things, like a property 
getter and setter.

mixin(Property!("Name", int));

creates a property named Name with type int.

I'd like to be able to call it like

mixin(Property!(Name, int));

(Name is a symbol but undefined at the mixin site(since it will 
be defined once the mixin is done)

I doubt this is possible in any way because it requires the 
compiler to allow such undefined symbols but would be nice...

e.g.,

template Property(lazy alias name, type) { ... }

but who knows, maybe I'm wrong and there is some way to do this?
