Description
I think that when we see fun1(fun2(x)) the function passed to transform should be fun1 \circ fun2. That way we can take advantage of more fast paths iirc.

Research direction
Start by tracing how transform handles nested expressions such as fun1(fun2(x)) and where fast paths are selected. Determine whether the requested fun1 ∘ fun2 composition fits the existing transform behavior; done means nested functions are composed for transform without changing unrelated cases and the relevant behavior is covered by tests.
