SwiftX optimizer

Is there any way to get the SwiftX optimizer to recognize user variables?
User variables usually are not literals as other variables are, so I've
not found a way to get match them using something like:
        OPTIMIZE user-var blah WITH user-var_blah

User variables usage usually produce subroutine calls, but assembly usage
of user variables bypasses the subroutine call and does indexing. I would
like to know if there is a way to bypass the subrotine calls using the
optimizer, and have SwiftX directly lay down the indexed access so that a
call is avoided.

Also, is there any way to optimize something using something like

        OPTIMIZE bleh LITERAL WITH bleh_LIT

or does it always have to be

        OPTIMIZE LITERAL bleh WITH LIT_bleh

I can do

        OPTIMIZE LITERAL bleh WITH LIT_bleh

and then

        OPTIMIZE blah LIT_bleh WITH blah_LIT_bleh

Maybe that is really the only way it can reasonably be done, because
matching LITERALS on both sides would get confusing.
