I think the Guile manual talks about it. I'll build the PDF of it and put it in my guile mirror's releases area after a few minutes here. There's an html version online.

item 1. conditional define(if (condition) (define a ...) (define a ...)) (define a (if (condition) body1 body2))note that semantics is not preserved: you do at runtime a check which should be performed only once at compile/definition-time. It is not clear that this is a wise choice. I would like to understand how to do conditional compilation in Guile-2 this is part of the matter. I remember having found something to specify that some form has to be evaluated by the compiler at compile time but I do not remember exactly right now. Anyway this change seems a bit odd….______________________________________________________________________________________________item 2. curried define
(define ((x a) b c) (display a) (display b) (display c)) (define (x a) (lambda (b c) (display a) (display b) (display c)))
and use cond-expand for backward compatibility
Still don't know what's going wrong. I will try to extract the wrong pattern.
Since it works in init-texmacs.scm but does not work in a module, I guess that the problem is related to Guile's Module System.

But in the module `tm-preferences.scm`, it will cause a compile error where I use `tm-define`.do you know what is going wrong? If I remember correctly my attempts to Guile-2 there were statements which were mixing compile-time and run-time evaluations (like for example conditional definitions) and they were not liked by Guile-2.Max_______________________________________________
