> Do we have line length restriction?

We're trying to stick to [PSR-2](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md), so quoting from there:

> There MUST NOT be a hard limit on line length; the soft limit MUST be 120 characters; lines SHOULD be 80 characters or less.

So yeah, you're right, I've split if to multiple lines. The alias names are common names for the same functionality, so imho it makes sense to add it where it applies.
