Absolutely.  As Chucks prime target of interest (hardware) uses LIFO
registers for stacks, only the top top one, or so, R stack items could
be used for restricted local storage (which is also common practice).

I accept that locals are useful, and would like to see hardware stack
engine implementations that support this better while retaining the
performance advantage of a stack cache implemented as LIFO registers
rather than in RAM.
