Question for #guile #scheme kings and queens.

I have a module A [(define-module A ….) ] and module B that's code-generated (not macros-way the writing strings to file way) that has [#:use-module A] statement in it.

At some procedure part of module A I want to import and use one variable from module B. I want it to happen only EXACTLY when this branch of code is called.

Is that even possible? Circular dependency = ⚰️ ?

@shegeley @wingo @fd9a @boo_@hako @simendsjo The evil secret version of things is that you can use @@

(define snarfed-variable
(@@ (my-project module-b) snarf-this-variable))

Though of course violating the abstractions of modules, there be dragons.

You might also consider putting a parameter in one module that's set and pulled from there.

In the future #guile on irc.libera.chat or the guile-user mailing lists are better places to ask these things typically!
