Selected Warning messages disabled in pylintrc: * unused-argument: Quite a large and disruptive change if enabled. * broad-except: Most required in-depth investigation to determine type. * fixme: Not important * protected-access: Complicated to fix * import-error: Too many false-positives * unidiomatic-typecheck: Should be fixed in the next round of checks. * unused-variable: Again large and disruptive changes. * global-statement: Most usage is required. * attribute-defined-outside-init: Should be fixed in next round of checks. * arguments-differ: Possible false-positives, needs revisited. * no-init, non-parent-init-called, super-init-not-called: False-positives? * signature-differs: False-positives?
