-[ ] Add CTRL+C handling to exec so we can break single-line loops.
This means we won't need it in outer loops, so you'll never see a
CTRL+C where a line doesn't actually exist.
-[ ] Add more checking to eval so that 2 2 + isn't a valid expression
-[ ] Fix up variable storage to match technical design docs
-[ ] Add floating point math support
-[ ] Add heap management routines
-[ ] Add garbage-collection routines
-[ ] Add more token routines to make it easier to scan forward
-[ ] Add a token routine to make it easier to indicate an expected token
with optional failure if the token isn't present. Failure always occurs
if a token is present, but it's not expected.
-[ ] Optimize assignments where possible to save ROM space
-[ ] Remove the monitor? (We're tight on space)
-[ ] Add support for higher-level language constructs using stacks
-[ ] Encode 32-bit integers as long words during tokenization
-[ ] Optimize keyword tokenization
-[ ] Decide whether to use brackets or parentheses for array indexes
-[ ] Add floating-point operations
-[ ] Add floating-point aliases -[ ] Better error handling: -[ ] Assignment to non-data register -[ ] Invalid comparisons
-[ ] Mouse -[ ] Power management -[ ] Debugging (breakpoints, etc.) -[ ] Sound
