You can access slot 0 to get it: (##sys#slot (##sys#make-structure 'foo) 0) => foo There's no official way to get at it. But, if you are on CHICKEN 5.1 the define-record-type type name will contain it: #;3> (define-record-type foo (make-foo) foo?) #;4> foo foo And it will be namespaced with the module if it is defined in a module. But beware, we might change the representation of record types to be objects instead of symbols at some point so we can add introspection to records. Cheers, Peter
