1) Strict type hinting helps to solve bugs, both the ones made out of careless/missing validation as well as subtle logic bugs that often take hours to resolve. I can tell you that within a week of implementing type hints we've been able to identify 30-40 bugs within a period of day. Many of which would not have been detected with "flexible" type hints that Paul is suggesting here is one example:

I think you might not have read what I suggested (it is different than the one I emailed to you privately). What you want is fully supported. If you must be passed an int, use the +int hint.

I'd rather use -int, then +int and make people who want loose typing do the extra bit, because native typing should be strict.
