That was a design choice.  It's because of this:

The trouble is that only works in a handful of simple cases 
(e.g., you just want a simple event counter that doesn't affect 
flow of control).  For anything else, you need to think carefully 
about exactly where the atomic operations are, so there's no 
point making them implicit.
