I don't think so. Just because other languages are looking at it
doesn't mean it will end up successful. It means it's an interesting
idea, that's all.

A litmus test for this PEP would be to apply it to a sizable code base
and evaluate the results. Looking at isolated function examples doesn't
tell us how it will scale (and I'm obviously not talking about
performance, but the ability to still give useful diagnostics in the
presence of typing "holes" - i.e. untyped functions - or imprecisions,
when factored in a complex graph of call dependencies).

Anybody can make predictions. As a data point, 6 years ago people were
predicting that the average desktop CPU would have 16 cores nowadays...
(we don't hear much from them anymore :-))
