You mean this ?
def actual_construction(n):
stuff
@cached_function
def is_construction_possible(n):
if whatever:
return actual_construction #just the function
return False
Two functions for each construction, two docstring, two sets of
doctests, AND a function that returns either "False" or a function ?
