Here's the abstract:
This SRFI provides two libraries for use with R7RS that provide
a way to sandbox the eval procedure to make it safer to use in
evaluating Scheme expressions of doubtful provenance. The
intention is to call eval, passing it an S-expression
representing a Scheme procedure and the environment defined by
one of these libraries. Since code evaluated by eval runs in a
null lexical environment, the resulting procedure can then be
invoked with less concern about possible side effects.

SRFI Editor
