I have a few notes unrelated to those I've already mentioned in the

1. Guile already has curried definitions in (ice-9 curried-definitions)

2. By turning your functions definitions into a macro, you've lost the
ability to use them in a first class manner.

3. I would strongly recommend _not_ using define-macro, and even more
so, not mixing define-macro and syntax-rules in a macro. Syntax-case is
as powerful as defmacro, and in most practical cases, about as much

4. What your macro does is not currying, it is partial
application. Those are different things. Currying refers to the process
of turning a function of n arguments into an n-nested set of 1 argument
functions. Partial application is, well, not supplying all the arguments
to a function. You can have partial application without currying, as
your macro shows.
