It might be worth clarifying what happens with: (eval '(define foo 1) (environment '(srfi 172))) The SRFI says that it specifies an "*immutable* global environment containing only specified libraries" which hints that trying to define anything in that environment is an error. (From the R7RS definition of eval: "If <expr-or-def> [...] is a definition, the specified identifier(s) are defined in the specified environment, provided the environment is *not immutable*." It'd be good to state this explicitly.
