 What Ben's working on now.
 --------------------------
 
-Expression parser/optimizer/evaluator revisions:
+Workspace exhaustion heuristics.
 
-	* Testing.
-
-	* Add random distributions.
-
-	* Get rid of Boolean/integer type mismatch errors.
-
-Procedures need to be able to make multiple passes.
-
-Write a better descriptive stats evaluator based on NR two-pass technique,
-revise all existing code to use it.
+Does SET work correctly?
 
 Update q2c input format description.

+Add Boolean type.

+Add NOT_REACHED() macro.

+Expressions need to be able to abbreviate function names.  XDATE.QUARTER

+Expressions need random distribution functions.

 There needs to be another layer onto the lexer, which should probably be
 entirely rewritten anyway.  The lexer needs to read entire *commands* at a
 time, not just a *line* at a time.  It also needs to support arbitrary putback,
