PHP - No Container libraries?
Most compiled languages that I have used have some kind of container implementation, Lists, Maps, Trees, Stacks and all their many variations. PHP has arrays and the SPL.
This post is more of a question than anything else, are there disadvantages that I can't see to having a standard container library for PHP? One problem that I can see is that containers built in user code will definitely be slower than a native implementation.
Am I overlooking something that already exists? Google fails me!
