Yes, I guess you're right about treating all operators in a strict way
with a simpler set of rules is more consistent.

Concerning the issue with copying existing code into a file that uses
stricter interpretation of the code: I think this should be regarded as
performing an upgrade of the code that is being copied. No problem in my
view.

In the section about widening the scope you address the type juggling
that happens on array access, like $array[12.34]. One could argue that
accessing an array item by key is implicit use of the == operator, just
like a switch statement is. I would love to see it included in the main
proposal in stead of proposing it as part of a different directive. The
change in behavior could be similar to what is proposed for the switch
statement: Array keys are compared using the === operator.
