# this is a bit brute force as the result is already 3x ast with wrapped 4x content

# at the beginning of a puppet run. TODO: Revisit for Puppet 4x when there is no 3x ast at the top.
# PUP-5299, some sites have thousands of entries, and run out of stack when evaluating - the logic
# below maps the logic as flatly as possible.
