variadic params for method

[zoryamba-work]

If we have a lot of parameters and want to validate them via some framework validators, it could be useful to let users to pass params to method as a variadic param. e.g.

public function methodName(...$params)
{
    // some validations here
}

It could be checked with ReflectionParameter::isVariadic method.

I could implement it and create a PR. Please, let me know, if this repo is still alive

Sure it is still alive, but hasn't had much love for a bit. A PR would be great - thanks
