Please bear with me; it's only about 7 a.m. in this neck of the woods
and I've had only 2 cups of coffee so far :-)
So one is calling some functions defined like:
def something1(..., afunc, ...):
if afunc(, 1.23, "plugh") is None:
def something2(bfunc, ...):
if bfunc(sys.stdout, "teehee", 0666) is None:
and there are so many xfuncs with different argument signatures and so
many times that the caller wants to supply a do-nothing xfunc that
defining a swallow-any-and-all-args empty() function is warranted???
Thanks in advance for any enlightenment,
