In other words, compiler is trying to be smarter than a 
programmer :)
With a poor result...
But... it is **main** function, after all!
Maybe, main() should be an exception when performing
that 'smart' optimizations? ;)

Btw, is there any dmd option for turning all/some optimizations 
off?
Or some 'pragma/attribute'?
