informatio from importer to importee

[Skaperen]

i was recoding the debugtoys module to work with a setup function. then i decided that instead of passing an environment variable name, i would expand the flexibility and pass the result of whatever test the importer wanted to be used, which might not be from environment variables at all. then i was thinking that logic could go around the original import like:

if eval(os.environ['ROSES_ARE_RED']):
    from debugtoys import pf,pr,pv,sl
else:
    def pf(*a,**o): return
    def pr(*a,**o): return
    def pv(*a,**o): return
    def sl(*a,**o): return

or maybe not. this setup function could also provide the dummy functions when the debugging is disabled. so i am recoding it that way now.
