I have a structure, that has a filestream inside it. File have to be cosed, when the structure is not used anymore (so gargbage collected).
Is the best way to do (require ffi/unsafe) (register-finalizer my-obj (lambda (x) (close-output-port (obj-file x)))) ? It seems doing right thing, but why `ffi/unsafe'? Is it OK, when my program actually doesn't use FFI? -- Roman Klochkov
