## Part B. Usable classes
Idea: allow using normal classes in the trait list.
Poking around in the archives, it seems there was a lot of discussion
about what exactly "horizontal reuse" should look like before the
current version of traits was added, way back in 2008. There were at
least 4 RFCs drafted with different versions:
- https://wiki.php.net/rfc/nonbreakabletraits
- https://wiki.php.net/rfc/traits
- https://wiki.php.net/rfc/mixin
- https://wiki.php.net/rfc/horizontalreuse
That last one, interestingly, has the implemented definition of traits,
but also a declined feature of "grafts", which plugged whole classes
together with slightly different semantics.
You might be interested to skim through those, and some of the threads
from the time (e.g. on https://externals.io) to see why they ended up
how they did.
