Subject: Re: [PHP-DEV] What do we need strict scalar type hints for?

I completely agree.
Strict typing doesn't fit into PHP. It was already told thousand times.
Check the second requirement in RFC template
https://wiki.php.net/rfc/template

Also, the only really useful case for "strict typing" is the ability to
catch mistakes in user apps.
However, this ability is really limited. Implementing "Design by Contact"
approach may be much smarter.

Thanks. Dmitry.
