Hi, The simple file
(format #f "~f" 'invalid) gives me FORMAT: error with call: (format #f "~f<===" ===>invalid ) argument is not a number or a number string FORMAT: INTERNAL ERROR IN FORMAT-ERROR! destination: #f format string: "~f" format args: (invalid) error args: (#f "error in format" () #f) ice-9/boot-9.scm:1685:16: In procedure raise-exception: error in format Is it expected to see 'INTERNAL ERROR IN FORMAT-ERROR!'? To me, that has a meaning similar to an assertion failure. Best, Jean
