Delphi was born 25 years ago (even more if we think of it as Pascal language) yet it has evolved into a modern language. Many features have been added to the language along the way and developers should try to master these additions and the coding techniques they enable.

Anonymous methods, generics, attributes and RTTI, record types features (operator overloading, implicit conversions), type helpers, inline variable declarations are just a bunch of topics we can delve into in order to fully exploit Delphi language capabilities.
