The complete spurious warning is:
equivs3e|1 F| F0002 <class 'AttributeError'>: 'Call' object has no attribute 'starargs' [pylint]
I gather it's got something to do with the new AST code in recent 3.x, and happens to some pylint's outside of vim's python-mode, but how can I get rid of that annoying warning inside of vim's python-mode?
It appears that python-mode brings in its own copy of pylint, BTW.
Oh, and I'm using the included vim-gtk3 on Linux Mint 18.1.
Thanks!
A very recent :PluginUpdate in vim fixed the issue for me. My guess is it was broken in python-mode for a while and they recently fixed it.
