3) add the ability to select the register allocator used, or disable it, within a sub. a programmer who knows what he's doing should have the ability to disable the register allocator and manage registers himself. the scope of the action must be limited to make the intent clear and to ease maintenance programming; it must occur at the sub level rather than at the file level. ~jerry
