# Things to ignore:
#   E128: continuation line under-indented (too noisy)
#   W601: has_key() deprecated (false positives)
#   E701: multiple statements on one line (colon) (we use this for classes with empty body)
#   E704: multiple statements on one line (def)
#   E402: module level import not at top of file
#   B3??: Python 3 compatibility warnings
#   B006: use of mutable defaults in function signatures
#   B007: Loop control variable not used within the loop body.
#   B011: Don't use assert False
#   F821: Name not defined (generates false positives with error codes)
#   F811: Redefinition of unused function (causes annoying errors with overloads)
#   E741: Ambiguous variable name
