I think this issue was mentioned by @ThomasLandauer in the past, and I was sure that we already had fixed it ... but I was wrong 😞

We use different variable names for similar code examples:

(1) return function(ContainerConfigurator $container) {

(2) return function(ContainerConfigurator $configurator) {

(3) return function(ContainerConfigurator $containerConfigurator) {

(3) is very rarely used, but (1) and (2) are used about the same ~50%.

So, which is your preferred variable name so we can always use the same for all code examples? Thanks!
