Hiho,
thank you for your responses.
This D language meta programming sounds funny and strange to
someone who has never really worked with something like this but
I understand its importance and will look more into working with
it. =)

Unrelated, but it may be of some interest. This isn't really a
good way to define your isSomeMatrix template, i.e., tying it to
a specific type.

This had worked perfectly in

As I understand it, Matrix is not a type; rather a type template. Only
instances of that template like Matrix!double can be used as types.

Hiho,
aww, that's a noob mistake of me.
Thanks!
Should take a closer look at the error messages next time a
should think more about their special meaning ...
It works now while it feels strange that I have to template the
three classes as I am only working with references to matrix and

This one's just nonsense.
or just

This one gives you the "used as a type" kind of error message.

Nothing really seems to work here.

I guess this is the culprit. You
Hiho,
I am currently working on a matrix library (matrices are
templated structs) and have just implemented so-called
"ElementalOperations" which perform certain tasks on mutable
matrices.
There is an abstract ElementalOperation where three different
ElementalOperation types inherit from. T
