Re: [racket-users] Distinct instantiations of modules

I think namespace-attach-module is one way to do this: #lang racket (module a racket (define ns (make-base-namespace)) (namespace-attach-module (current-namespace) 'racket/promise ns) (parameterize ((current-namespace ns)) (namespace-require 'racket)) (define *promise? (namespace-variable-

[racket-users] Distinct instantiations of modules

Some (I think many) modules define struct types and provide the constructors and predicates of these structs. A predicate of an instance of such a module does not recognize a struct made by a distinct instance of the same module. For example: #lang racket (module a racket (define ns (make-base-n
