Source Code with Construct

from __future__ import print_function

def calledRepeatedly():
# construct_begin
    return (lambda x : x)(7)
# construct_alternative



import itertools
for x in itertools.repeat(None, 50000):
    calledRepeatedly()

print("OK.")

Source Code without Construct

from __future__ import print_function

def calledRepeatedly():
# construct_begin

# construct_alternative
    return 7
# construct_end

import itertools
