Description
Example: a transducer that appends :foo to the result of the reduction:
In Clojure, the above code yields
. In ClojureScript, it results in an infinite loop. The same happens with `eduction`.

following commit to Clojure, which replaced `LazyTransformer` with
`TransformerIterator`, effectively making the transducer behavior akin to the
one in Clojure.
