It's a little hard to tell what you actually want from your description,
but it looks like you're fighting the language unnecessarily here.  If
you have a sequence of functions that you want a sequence of results
out of, you should be thinking in terms of a sequence type.  A list,
in other words.

results = []
for f in fn1, fn2, fn3:
     results.append(f())
