You can use recur to build a hierarchy. What do you mean by you can't use it as it is not the last statement?
I have used recur in all sorts of places in the fn, without noticing any restrictions, and built hierarchies. I am no expert so I may have been conforming to the restrictions accidentally, but the only thing I have ever had to be conscious of is wrapping my arguments into a vector when recursing a function with & arity.
