Awesome thanks for using this and creating a PR!

I see Travis is complaining about PHP 5.4 and 5.3 because of your type signature change. Do you need to add the callable declaration or is this not needed perse? If not maybe you could revert that and then I can release it.

If it is needed I have to drop PHP 5.4 and 5.3 or find a workaround.

Hey, @mac-cain13. As I see, Symfony 3.0 requires php >= 5.5.9 (https://github.com/symfony/symfony/blob/3.0/composer.json#L19) and can't be installed to container with 5.3/5.4
I don't see any other solutions except drop PHP 5.3/5.4 support, or drop symfony 3.0 support.

[mac-cain13]

Yeah, alright we should drop the older PHP versions!

👍

This is now in the 1.3.0 release!

1.3.0 not only drops older PHP versions, but also older Symfony versions: 2.7 and 2.8 are incompatible with the new setCode() declaration.

Arnaud is right about the breaking changes. They should be in a 2.0 with a clear notice that it's symfony 3 only and drops PHP versions.

I'll fix this later today. Sorry for the confusing you with not so semantic version numbers and breaking changes!
