Local method variable marked as "ambiguous" when it should be locally scoped

[madig]

1. Index https://github.com/fonttools/fonttools/tree/master/Lib/fontTools (install in local venv with pip install -e .[all]
2. Navigate to fontTools.varLib.merger.Merger.mergeTables:

    def mergeTables(self, font, master_ttfs, tableTags):

        for tag in tableTags:
            if tag not in font:
                continue
            self.mergeThings(
                font[tag], [m[tag] if tag in m else None for m in master_ttfs]
            )

Sourcetrail or an underlying library goes off and marks tag as ambiguous and points to other classes like AxisDescriptor etc., when the variable should clearly be locally scoped: Or am I missing some Python scoping nuance here?

Thanks for reporting @madig! This is a known issue and already open with #26. Closing due to duplicate
