With Ivan's approach, you lose access to the actual lambdas, so you need
to create a new function and then modify its code object to actually call
the code; this seems a little clunky to me. You might instead want to
wrap the lambdas in an object that will do the comparison you want:
class Code(object):
def __init__(self, func):
self._func = func
def __cmp__(self, other):
return cmp(self._func.func_code, other._func.func_code)
def __call__(self, *args, **kwargs):
return self._func(*args, **kwargs)
func_set = set(Code(f) for f in funclist)
