Option A makes `take` lazy, so the §6.3 counter tests must force the take
result (dorun) to drive realization — an unconsumed take correctly realizes
nothing. With that, all 37 lazy-infinite cases pass and the minimal-realization
counts match (proving the Option A transformers realize exactly the demanded
prefix).
interleave kept eager: a lazy (cons-recursive) version leaks its lazy-seq macro
expansion under :compile? — the same jolt-r81 bug that blocks lazy reductions/
tree-seq. Documented in 20-coll.clj.
Gate: conformance 246x3, lazy-infinite 37/37, fixpoint, self-host, specs+unit
green.
