Late binding means that the compiler doesn't have to be able to
figure out at compile time whether or not a particular object

Speed.
What is "late binding" exactly ? What are you binding ?

Templates can save typing. People are demanding them, because there is a
hype. Lack of templates is seen as a deficiency of Pascal against C++.
So we should support them.

Agreed. I have a 2000 lines unit containing type safe lists that would
become 300

Certainly I do agree. However, they *will* be used to introduce the

That is true. Yet I really like the type-safety of templates. Advantages

Yes. Otherwise they are no templates.

IMHO this can't be done. E.g. the avoiding of multiple insta

Probably the best example of this is something like TList:

Hello,
I am trying to understand what exactly generics are. I read the wiki
page, but there are lot's of code examples and very few explanations.
Can someone explain it to me in a (relatively) simple way?
What problem is it trying to solve?
And how do generics relate to interfaces?
thanks,
