Hello,

I just realized it now (I brought it up in a different manner when
there was discussion about the RFC), but I didn't notice there was a
totally false statement about it in the RFC itself. You probably
should fix it. I'm speaking about the "Strict type checking, which is
used by many popular programming languages, particularly ones which
are statically-typed, such as Java, C#, Haskell, or Facebook's Hack.
It is also used for non-scalar parameter type hints in PHP. With this
approach, an argument is only accepted if its type is exactly the same
as the parameter." paragraph.

This is NOT true (at least for C# and Java), as you can read here in
the documentations of respecitve languages so you should not compare
the strict version of the typing implemented in PHP with other
strongly typed languages, because the PHP's "strict" is stricter than
strongly static typed languages. I really hope noone voted with the
thought that the strict typing acts as it does in Java and C#.
