I was attracted to Python in 1998 because it seemed designed to make the simple cases simple, and the hard cases possible. My personal takeaway from this discussion: I will continue to advocate for the use of Ellipsis as a sentinel in the *many* cases where it is suitable. For the hard cases, I will read the upcoming 46-page "PEP 973: Parameterized Sentinel Factory Factory API" ;-) Cheers, Luciano -- Luciano Ramalho | Author of Fluent Python (O'Reilly, 2015) | http://shop.oreilly.com/product/0636920032519.do | Technical Principal at ThoughtWorks | Twitter: @ramalhoorg
