I understand that, as its documentation clearly says, `immutable?` is not implemented for `struct`s. (In the sense that structs aren't on its special list: immutable? returns #f even for a struct that does not use #:mutable.)
Is there some other way to check at runtime whether something that is struct? is mutable or not? p.s. The background for my question is an implementation of `egal?`: https://github.com/greghendershott/rackjure#egal ____________________ Racket Users list: http://lists.racket-lang.org/users
