[TYPO3-core] RFC: #11438: Add a registry to t3lib

[Steffen Kamper]

Hi Ingo,

i really like the idea of the registry. I read the posts and i also 
would vote for namespacing. This also would avoid key conflicts.

A general question: what is the difference between the registry and a 
cache? I mean it's used the same way storing a value with a key 
(namespace would be the tag).
i don't mean cache that will be cleared with "clear all cache", but 
cache has the advantage of using different backends.
Suggest: i want to use a registry in my extension, but with SESSION 
instead DB, or memory. In case of cache all is already there, only a 
config has to be made.
