DISCLAIMER: These notes are from the defunct k8 project which precedes SquirrelJME. The notes for SquirrelJME start on 2016/02/26! The k8 project was effectively a Java SE 8 operating system and as such all of the notes are in the context of that scope. That project is no longer my goal as SquirrelJME is the spiritual successor to it.
With the meta macro stuff, it may be possible to optimize meta macros when the code is being generated.
Extra notes could be added to the assembly methods (which is what the macros will point to) to indicate how they function. So it would be a post assembly optimization. However, this is just an idea.
