I have some nested templated code that takes function pointers.
In many cases I pass it functions of identical signatures,

care about the `@safe`-ness and I'd really like to just have
them all treated as `@system`, with one instantiation per
unique signature.

My current solution involves some very gnarly string mixins.
I see what you mean, in the past I wanted `cast(pure)`,
`cast(nothrow)`, similarly to avoid using metaprog (or maybe was
that delegates) in certain case.

But surely there has to be a better way?
No.
