Below is the definition of bytevector->pointer in libguile/foreign.c:

Hi Jean,
You could just turn that into a syntax-case macro, use gensym to
generate the names, and insert them using with-syntax or quasisyntax.
Yes, this is what I ended up doing before I saw your other reply.
By the way, I'm rather confused as to why you deem this caching

Well, as Guile-SMC is a tool for making tools, I think that Guile-INI
could serve as a good example of what Guile-SMC can do.
Here, you can see the finite state machine (FSM) description in PlantUML

This release fixes some new-found bugs, namely in the state-machine
profiler. Also now it's possible to specify "pre-action" and
