tupleof will do what you need (mostly). However, I don't think
there will be
any way to (generically) run-time zip on the members, due to
probably type
mismatch, and memory layout. In any case, nothing trivial,
AFAIK.
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.
One issue with this is that it will allocate a copy of all the
elements. This may be fine if the elements are meant for a
"read-only" operation. But it won't solve the issue if there are
any mutating operations.
Just saying.
