Re: Unbound variable warning/exception

[Massimiliano Gubinelli]

Thanks, there is indeed some interesting and useful code there. 

However I would prefer not to make large changes in this moment.  I removed 
most of the warnings by proper use of modules but we still have some circular 
dependencies among modules and these are sources of some warning which for the 
moment I just want to silence. I think as long as they are warnings there 
should be the option to suppress them. There is no error in the code, but the 
current way circular module dependence in guile is handled does not recognize 
it... 

Best,
Max
