If I have a variadic function such as in

    haystack.find(needles)

what options do I have for defining needles in compile-time outside of this expression and call find() with this definition as arguments possibly multiple-times?

Is std.typecons.Tuple my only option here?

Further, is it possible to operate on this parameter set in compile-time such as in my case reversing all the arguments before feeding them as a variadic set of function parameters?

I need this in my module

https://github.com/nordlow/justd/blob/master/skip_ex.d#L122

when implementing skipOverBackShortestOf who needs to call retro on each of the needles.

I just found out that Tuple member expand does what I want here.

I cracked skipOverBackShortestOf too at
