I'm trying to do something like a fold, but over a tree instead of a list.
Is there anything like that?

If it's unclear what I mean, there's a mechanism like that in guile:

They use it e.g. for XML transformations, but it's really a generic
operation and quite useful.

Here's a paper on it by Andy Wingo if anyone wants to know the theory


is there anything along those lines in Racket ?

Thanks in advance
