# not include "unused_" and "ignored_" by default?

[DESIGN]

# NOTE(nathaniel): Not particularly attached to this value; it just seems to
# be what works for us at the moment (excepting the dead-code-walking Beta
# API).

[MISCELLANEOUS]

# NOTE(nathaniel): We are big fans of "TODO(<issue link>): " and

# and thus existing member attributes cannot be deduced by static analysis. It
# supports qualified module names, as well as Unix pattern matching.

# TODO(sergiitk): remove when astroid upgraded to astroid 2.15.5, see
