Hmmm...now you have me very intrigued. What is a use-case where
you'd want to use a non-static embedded class? Sorry if I'm

Hello
I have this weird error trying to achieve something simple:
module list_test;

template Id(alias a) { alias Id = a; }
template ParentOf(alias member)
{
alias ParentOf = Id!(__traits(parent, member));
}
template wl_container_of(alias member)

void main()
{
wl_container_of!(item.link).get(); /* Error: 'this' is only
defined in non-static member functions, not main */
}
I'm not sure what's going on here, if this should or shouldn't
work. The error message isn't exactly good.

This may be the cause of your trouble. If the nested class references
members in the outer class, then moving it outside will break it, since

Hey everyone,
I, once again, have a problem with an error I can't seem to figure out!
The situation:
- a class, inherited by five other classes;
- the class having a static function which returns one
if its subclasses depending on the input of a string.
Something like this:
