Why this horrible trick has to be used:

cast this as (T) in a function template that's been mixed in an
ancestor is not always usable,
Alternatively, you can use a static method and pass in the
instance.
Note that `new B` will print A's members twice, because A's
constructor is always called and `__traits(allMembers, B)`
includes A's members.

If the mixin has to be used on class and on struct, I cant use an

there.
Templates are not

Indeed, this is a good answer too.
The difference between this and the template thing I did is that
yours is virtual so calling it through an

Initially this solution looked awesome but when `bug()` is
static, `` returns some functions, not some delegates, which
is a problem: this implies that I have

One last question: is it possible to nest the calls to
