My understanding is that there can only be at most a single composite construct
when decomposing any given compound construct. So there wouldn't be a "first"
composite range, but rather one composite range or none. In fact, if there is a
composite range, it must also be at the end of the construct.
So, something like this: `<composite-construct><other-leaf>` can't happen.
Decomposing a single compound construct into a list of leaves while keeping
composite constructs as a unit should be as simple as forwarding all
block-associated leaves until finding a loop-associated leaf and then
aggregating (via `getCompoundConstruct()`) everything from there until the end
of the leaf list to append one composite or single loop construct.
