But how do I create a sub-class overridable class variable? Here is an example of what I would do in Python: class Fish: var = 'fish' def v(self): return sel...
I know that class variables are declared in memory (as opposed to on the stack) when the class is initialized, and I know how class methods are basically used. But I have some questions about class methods that aren't answered in the basic documentation. Are class method also declared in memory? What about any object declared within the...

Basically, I want to con...

I've always wondered about this for a bit, but why is operator overloading not available for classes in Delphi? I remember reading an answer once while on the run, and it said it would come in conflict with something, but I can't remember much. As far as I can tell, only the implicit operator may cause a bit of problems since classes ar...

This would essentially make records the stack-allocated version of classes, just like C++ classes, and would render "objects" (note: not instances) obsolete. I don't see anything problematic with it. T...

I am working on a cache class, I would like to be able to set and get cached items from 5 different storage mediums. Memcache, APC cache, file cache, sessions, cookies. Maybe even a 6th (database could be added as a 6th). My goal is to make this flexible enough that I can use it in the future on many projects very easily (portable). ...
