It would be possible to do, but definitely fairly low priority given the amount of flash space left. I don't think it comes up enough in terms of everyday usage for the amount of flash it would take. (For what it's worth, I think the HP 35 also gives an error: it's one of the examples given in the "The New Accuracy: Making 2 ^ 3 = 8" in HP Journal.) My current priorities to fill the flash are approximately in order: trig, "continuous memory" by storing to flash when turning off (all the flash/eeprom is in-application-programmable on the microcontroller used apparently), auto poweroff, resistor color code decoder, hex/dec converter, and then special cases. Probably possible to free up space elsewhere, but there aren't many easy, major changes I can think of that would magically give a large amount of space back (i.e. similar to switching functions to not be re-entrant and not pass pointers).
