Not going to happen! I guess an op code could be added that would
allow such a feature but the underlying architecture would make it a
nightmare. Another reason von Neumann architecture is superior to
Harvard - IMHO.
To execute the code (as machine code, not interpreted), it would have
to be placed in flash.
Besides scarcity (the interpreter is probably using just about every
word!), there is the possibility that the downloaded code would
disable memory protection and make the underlying interpreter code
visible. In fact, it wouldn't even have to do that; it could just
read the code, word by word, and pump it out the serial port. So much
for intellectual property rights.
