It's somewhat like static this, which is inflexible in how you write it.

It is not documented in detail but it is there =).

Why you need a type tuple? Can't you do:
foreach(np; [1, 2, 3, 5, 10])
That is a runtime foreach, so no. If the argument is a TypeTuple, the compiler
evaluates the foreach as a static foreach, effectively duplicating all code in
its body and filling in the constants/types in

Nice, but isSpinnable is always checked twice with your approach.
Right. But isn't the compiler able to optimize away this inefficiency?
I would like an explicit static foreach better though.

Nope. You don't get a guarantee from the language that your code will be
optimized
in a certain way.
That said, dmd/gdc are _not_ able to do
