# Pylint fails to suppress STDOUT when importing whitelisted C
# extensions, mangling their output into the expected JSON which breaks the
# parser. The most prominent example (and maybe the only one out there) is
# pygame - we work around that by asking pygame to NOT display the message upon
# import via an (otherwise harmless) environment variable. This is an ad-hoc
# fix for a very specific upstream issue.
