What version of Symfony are you using?

closing, see #9 (comment)

that's too bad: I think the issue is not in the upstream, because service definitions are NOT case sensitive. It just happens that newer version of Symfony generate the xml manifest with the original case instead of applying strtolower. This library should NOT treat service names as case sensitive.

[lookyman]

Ok, I'll reconsider it...

[jvasseur]

because service definitions are NOT case sensitive.

That's false, services id are case sensitive since Symfony 4.

That's false, services id are case sensitive since Symfony 4.

I see. That's not the case for Symfony 3, still.

[stefanotorresi]

I guess I'm gonna have to give up on this, as it's not forward compatible with SF4 and granting compatibility with both 3 and 4 is out of the scope of my original intent.
There is ground to build a use case for a separate check about this, since class names are not case sensitive and they are commonly used as service ids; see this discussion.
Thanks for your input, @jvasseur!
