You can turn the tuples into ranges with `only`:
writef("%(%(%s %)\n%)", zip(indexes, source).map!(t =>
only(t.expand)));
This is a nice idea. Expand can probably be replaced by a []. I
presume this works only if the types inside the tuple are the
same.
Expand creates "returns" a TypeTuple though, so it's arguably
"free". "[]" allocates a dynamic array, so is costly.
On the flip side, "only" is *entirelly* by value, and carries all
its arguments. If the tuple is big, then the range can become
quite big.
