Research direction
Start with gyp/pylib/gyp/common.py at line 456 and review the linked Python Guide explanation of mutable default arguments. Confirm how the function is called and identify the intended non-shared default behavior. Done means the default no longer persists mutable state between calls while the existing behavior remains intact.
