Needed:
- - Must test vectors on expressions.
-
- - Test range syntax (VAR00 to VAR99).
-
- Warnings on domain errors (see "Domain Errors" in SPSS manual)
and documentation of such.
- - Test generic optimizations for correctness.
-
- - Update top-level TODO.
-
- Finish polishing code. Many functions need comments.
- Test the remaining statistical distributions.
- Implement unimplemented functions.
+ - Check treatment of 0 bytes in expressions is correct.
+
Extension ideas:
- Short-circuit evaluation of logical ops
