Why Wing marks multiline tuple of statements as Syntax Error, but debugs and runs it just fine?

edit

I hope the screenshot is self-explanatory:

Why are there red squiggle underlines on coma in line 1, on whole line 2 and on ")" in line 3.

There is no syntax error here really! It works just fine in Python and does not show me an error in IDLE Python or in PyCharm.

Please fix it if possible.
