# Crude, totally-not-usable-in-the-real-world code to remove optional
# parens from control keywords.
#
# In a perfect test scenario we'd simply make this a no-op, to demonstrate
# that the bug happens when any rewriter is loaded regardless of whether it
# actually changes anything but that makes assertions much harder to get
# right. It's much easier to just show that the file did, or did not
# get changed.
