You are right.. I just have wishful thinking of the compiler 
being smart enough to auto-fix some things, but when you start 
making assumptions then errors and problems tend to arise more. 
That and if the compiler DOES reorder those blocks, then you 
re-ordering them for a specific reason may not work and could 
have unintended results. Course I don't see how with Try/catch 
since only one block (plus finally) can be used at a time.
