Silenced deprecation errors

[GrahamCampbell]

This will fix all the issues people have been posting recently. Firing silenced deprecation errors is the convention. See, for example, Symfony. :)

I already explained before, that's not the approach I want to take for this package.

Deprecations aren't errors and shouldn't be treated like errors, regardless if they come from the language or from a lib.

Thanks for your time on sending this PR, though.

I am confused as to your approach here. Aren't you treating them like errors?

[lcobucci]

@GrahamCampbell I'm treating them just like the language does. Please read carefully the explanation I gave on the issue (and on click the links).

Hmm, I still don't think I agree that is the best approach, from a practical perspective.
