hijacking this thread...

Blindly retrofitting all foreach loops to use lambda instead will cause 
you some perf trouble,
because the VM JIT is currently not as good as optimizing lambda calls 
as it optimizes loops.

If you have few elements (<10 000) you should not care because otherwise,
it's better to keep the good old for each loop, at least for now.
