I had firsthand experience with this otherwise useful feature masking an obvious bug. In one codebase there was function along the lines of (for calling into MSSQL with it's "peculiar" stored procedures): def call_stored_procedure(name, **args): cursor.call_proc(name, *args.values()) Of course this is obviously wrong and on Python 3.6 this will break horribly on first use, while in Python 3.7 this worked as long as the keyword arguments were in the correct order.
