The introduction of generics and their abundant use in Delphi has noticably slowed down the compiler and increased binary sizes. To my dismay, compile times of 20 seconds up to 2 minutes have become not uncommon in Delphi. Something almmost unthinkable in D7 days.

With these generics they copied all the problems of C++. One of the worst ways of doing that

It would have been better to implement them like dynamic arrays. The generic code gets RTTI, the specialization does not generate any code, and just avoids explicit casting.

That would also be a much less flexible approach. The way it is now allows for much more functionality to be covered with generics.
