This is better for performance because these then don't need to be reevaluated every time they are called.
When encountering an unqualified function or constant reference, PHP will first try to locate a symbol in the current namespace by that name, and then fall back to the global namespace.
This short-circuits the check, which has substantial performance effects in some cases - in particular, ord(), chr() and strlen() show ~1500x faster calls when they are fully qualified.
However, this doesn't mean that PM is getting a massive amount faster. In real world terms, this translates to about 10-15% performance improvement.
But before anyone gets excited, you should know that the CodeOptimizer in the PreProcessor repo has been applying fully-qualified symbol optimizations to Jenkins builds for years, which is one of the reasons why Jenkins builds have better performance than home-built or source installations.
We're choosing to do this for the sake of future SafePHP integration and also to be able to get rid of the buggy CodeOptimizer, so that phar and source are more consistent.
- nametag visibility flags don't work properly, only players show them all the time
- invisibility overrides nametag visibility
- scale 0 triggers asserts on debug builds
..... how hard is it to NOT break these simple things each update Mojang?

Seems :shoghi: used stdClass to silence IDEs, which before ALPHA5 would complain about myriad undefined fields due to lack of type checking (switch based on packet id 🤦)
