Re: [Texmacs-dev] Overwriting definitions with tm-define

Hi Giovanni,
 very likely "translate" is already defined otherwise and overloading it with 
different number of parameters is not possible.

I think this speaks for a request I was making to Joris, that is to distinguish 
the *definition* of a new overloadable function and its *overloading*. Both 
operation are currently handled by tm-define but from my point of view this is 
not very nice. Especially because the tm-defined functions are by default 
imported in all texmacs modules.
