it's used in (which determines which variables are in scope inside the eval),
and it's easy to miss compilation errors, since eval catches them and sticks
them in $@ instead.  This module attempts to solve these problems.  It
provides an eval_closure function, which evals a string in a clean

errors are rethrown automatically.")
