Referenced Cells Extension

Fingerprint 0x52454643 ('REFC')

Under development.

The REFC fingerprint allows vectors to be encoded into and decoded from single scalar cell values.

After successfully loading REFC, the instructions D and R take on new semantics.

R 'Reference' pops a vector off the stack, and pushes a scalar value back onto the stack, unique within an internal list of references, which refers to that vector.

D 'Dereference' pops a scalar value off the stack, and pushes the vector back onto the stack which corresponds to that unique reference value.

The internal list of references is considered shared among all IP's, so a global static can be used to store this list, so that this extension remains tame.
