Example of defining and using exceptions

Dear guile hackers, I would like to use the "new" exception style in guile, i.e. define- exception-type and friends. However, I don't understand how compound exceptions work. Do you have an example of using exceptions, showing what compound exceptions can bring? Best regards, divoplade

Implementing a "write" method for self-evaluating objects (by equal?)

Hello guile users, In the manual, I read: (define-method (write (file ) port) (format port "#< ~s ~a>" (name file) (fd file))) So it is possible to define a write method for foreign objects (and more generally GOOPS classes). My question is: why use such a bizarre syntax with # and #:fd ~a #
