Ryan,
You'll find a couple threads earlier this year in heated debate about
interface delegation and how it is implemented. My conclusion was to
avoid interface delegation - there are just too many traps for the unwary.
There is also another thread bemoaning some odd features about the
"supports" function.
In use, once you have a variable containing a reference to an interface,
it behaves, for the most part, the same as a reference to an object
supporting the same methods and properties and should be used as such.

I did some experimenting this morning and found out I could pass references to
the interface and call methods directly without using Supports and incurring
the string compare penalty. There’s also interface delegation I read about and
using “implements” keyword but I couldn’t understand what the purpose of this
is and why it’s even useful.

Some times when I want to communicate with a class I don’t have full scope
access to I’ll use interfaces and the Supports function to call a method. I’ve
noticed however that the string compare function that it is used to find the
interface in the class is very slow and makes them not useable for high
performance situations. Is there a better way to do this or should I not use
interfaces like this in FPC?
