I see now, thanks. The only thing which I am a bit concerned about is the
complexity introduced by this change, in the sense that it is relying very much
on the `bind` implementation of each expression. I think it would be great if
we could generalize it.
Can we add a generic function similar to the `createLambda` in the analyzer
for this?
