Oracle 11g new features, part 2

There are two new interesting sources for 11g new features.
Tim Hall post The Next-Generation Self-Managing Database (11g)
And Lewis Cunningham post OOW: Enhancements in Oracle 11g PL/SQL
Also these features or enhancements seems very promising

1. PL/SQL Native Compilation. There is no need for external C compiler, so it’s easier to make PL/SQL faster.
2. New Data Type: simple_integer. Another performance booster.
3. Intra-unit inlining. - this is feature that I was missing for years. Now I can create complex expressions and reuse it easily. I hope it will work also in SQL
4. Database Replay and SQL Replay - this is very interesting idea.

I'm looking forward to play with these features.
