Haskell & RPL

One nice feature of Haskell is that it generates C code. So if one were, hypothetically speaking, intending to produce an entirely new firmware for a calculator like the 50G, then writing a new RPL in Haskell rather than directly in C would result in much more rapid development times, with rather fewer bugs and more easily automated testing.

So don't port Haskell to the calc, but use it to develop a new calc. As I suggested in another thread previously, FreeRTOS provides a nice OS base and any new RPL implementation can run as an app on top of it.
