My matheval will do this.  I don't think I've updated the lib proper, but I've
written a booleval.e extension to it to do boolean evaluation.  Within the lib,
you set and clear variables.  If a necessary variable isn't defined, it won't
finish evaluating, and it's easy to see, since a fully evaluated statement is
either returned as 1 or 0.

You can get the files in the last update on my page to EuSQL:
