It might also be more useful to have it more granular than

Why am I thinking of the "register" keyword in C?
My email was concerned with storing/retrieving multiple variables
with a single lookup, not with hinting to the compiler.
I guess my point was than that it maybe would make sense to be able 
to hint to IMCC, so that IMCC can do a better job of grouping 
variables together.

Please ignore me if I'm not making any sense.  I'm just coming down 
after a _long_ day and may not be thinking too clearly anymore...  ;-)
