Thanks. Now since I can't do `takeOne` on `Group`[1], exactly
what kind of range is `Group`?
[1] Error: no property 'takeOne' for type 'Group'
When you downloaded DMD, you also received the source to Phobos,
so you can see for yourself. The only Group type I see the
chunkBy implementations is at [1] (the link to the github viewer
probably won't point to the same place for long, but you should
be looking in the the version of ChunkByImpl for forward ranges).
It's a forward range.
Do you have some sample code that shows the error?
