I agree wholeheartedly about the variable limitation.
If someone wanted to enhance the Lego firmware to add a few new bytecodes
for additional global and local variable space, I'd consider enhancing NQC
to take advantage of them when present. If effect, NQC could target two
different platforms - standard firmware and enhanced firmware. Such an
undertaking may be easier than completely new firmware and/or tools.
