It’s also worth noting that if you do want strict typing in PHP, you now have an alternative:
Hack. Hack even allows you to mix strictly-typed code with non-strictly-typed code if you want. But
PHP is not going to go in that direction. This RFC offer rather strict validation of input to a
function, but it does not offer strict *typing*, as strings and floats, where interchangeable, are
accepted.

Isn’t a must, surely? (I assume that was a typo)
