This would also be okay, and even a preferable solution, but how?
Currently I evaluate the user functions via this method:

SCM EOS::Guile::EvalCatch(SCM& proc) 
    return scm_catch(SCM_BOOL_T, proc, fErrorHandlerProc); 


fErrorHandlerProc = gh_eval_str("(lambda (key . args) "
    "(display (list \"Error in proc:\" key \" args: \" args)) (newline))"); 

Maybe this isn't the best way to do things, but how might I catch just
divide-by-zero in order to plot the vertical line but have all other
errors handled with this generical warning?
