An AssertionFailedException must be a Throwable

[Ocramius]

Since Throwable is also available starting from PHP 7.0, bumped dependency
requirement, as 5.x is being retired anyway.

Build fails due to implicit PHPStan upgrade - probably a good idea to lock it down to ^0.9.2 for the time being

[Ocramius]

PHPStan now locked to ^0.9.3

I'm going to deprecate support for PHP 5 in line with PHP, end of 2018 - http://php.net/supported-versions.php.

@rquadling that sounds... kinda terrible tbh, considering that people should really just rush to 7.x

The library currently operates well. It is a shame that there are no metrics from Packagist that would allow package developers to know what versions of PHP are being used. Whilst it may not be a perfect score, having some ballpark figures would certainly be useful.

As for forcing people to move, I'm never a fan. There's little in this library that warrants deprecating support for PHP 5. If this is a critical feature for some other package, then a polyfill could do the trick.

OK. Metrics dictate!
