In my efforts to write a new DIC, it seemed prudent to use Dice as a starting point as I have contributed to it previously and understand it well. However, there are a lot of other DIC libraries out there, and they often vary quite a lot in how they work. This is probably a large part of why PSR-11 only specifies two methods that all DICs should be able to agree on.

I intend to use this space to document my research into the paradigms used by other PHP DICs I can find, which will inform my further development of this library. Under each heading I will list the principles underpinning each library and a bit about how it accomplishes them -- along with any opinions I may have about it.

One resource I've used in compiling this list of libraries is kocsismate's benchmark. However I am only including libraries that are already somewhat close to doing things the way I prefer. This is why I have excluded Pimple, ChubbyPHP, and Disco.
