In this way, RefleX is not a VM : few times ago, I was generating some
Java code from XML, but it appears that pre-compiled classes were doing
almost the same job.
However, I'm still thinking on a way to mix Java code within XML tags ;
of course, such parts will be compiled. Maybe in a next release ?
