You can define a map-like (or zip-like) template to act on tuples as
if they were ranges, but the resulting type will still be a tuple: in
general, the members and the delegates associated with them will all
have a different type.

Bioinfornatics, if you know your struct members are all of the same
type, you can 'cast' the tuple as an array by wrapping it in square
brackets like this:

[ myStruct.tupleof ]

and then use the usual range algorithms.

If that's not the case, you can create another struct, holding both
the original struct and the delegates...

I did some generic range-like work on tuples a few years ago. See for example:

Could you explain what you want with more details?
