[Texmacs-dev] Guile modules and redefining functions

[Leo]

Hi All,
For the sake of displaying labels I have to redifine 
make-inactive-label functions. In TeXmacs-1.0.1 the following
definition placed in my-init-texmacs.scm did the job
 
    (define (make-inactive-label) (make-expand-arg "label"))

However, this redifinition has no affect when used with TeXmacs-1.0.1.10.
I suspect that it is related to guile module system which is now being used.
I am completely unfamiliar with guile and its documentation really sucks.

Anyway, how could I redefine a Guile functions previously defined somewhere
in TeXmacs at global scope or exported from some module??
