No description provided.

In addition, fix bug in fold that was turning asserts into checks.

More typechecking still needs to be done.
Check that the operand in a constraint is an explicit name,
and that the operands are all local variables or literals. Still need
to check that the name refers to a pure function.
Also added the --batch flag to texi2pdf, as it doesn't really ever
seem useful to drop to the TeX prompt during a build.
This commit reinstates the requirement that the predicate in a
"check" must be a manifest call to a special kind of function
declared with the new "pred" keyword instead of "fn". Preds must
have a boolean return type and can only call other preds; they
can't have any effects (as enforced by the typechecker).
The arguments to a predicate in a check expression must be
slot variables or literals.
