That's the wrong approach to improving performance. Measure first, then 
change. In most cases the real bottleneck is not where you expected it 
to be.

If you have a begin..rescue..end block inside a *very* tight loop 
executed thousands of times then maybe it would be worth removing it - 
but on the other hand, if you end up replacing it with more if.. tests 
and method calls, then you could end up making it slower anyway.
