Whoa, that's quick! 🚀

👍

This should be placed somewhere below, where we talk about constants as parameters

@wouterj It is true for all parameters, not only for constants (it can hurt you for class names too for instance)

@wouterj like@stof said it is true for every type of parameters. But maybe I hould change the example to make it clearer?

Perhaps I should add a classname parameter?

Well, make it indeed easier to understand. What about taking the mailer example? Settingmailer.transport tophpmail.

And after that, can you please squash your commits (if you know how to do that)?

Done, I added the exact value of the retrieved parameter, so we can see the line returns and spaces, and I also added a note on constants and class names which can throw exceptions.
The commits have been squashed into one.

👍 great note Loïc (and a clean PR)! I've patched this into the 2.2 branch at sha:1b707dd

Thanks!
