I attempted to read this one out of curiosity, and it raised a question: is there a way to write these unsafe functions (List.Unsafe.tail/head...) in pure OCaml? this code: let head (Cons (a, b)) = a would still generate code that check input constructor in order to raise an exception if it's not Cons (-unsafe command line parameter does not change this, regretably, according to the manual). Is there another way? -- Caml-list mailing list.
