Could you refer me to a good introduction-intermediate level resource to learn modern Pascal? I currently work on my projects in C (quite fluent) and am constantly looking for a language that offers proper type safety, generics and a good module system without being overly complex (eg, C++). Pascal and Object Pascal seem like a really good fit but I can't get my hands on a high quality walk-through of the language implemented by FreePascal and its standard library.
