If the evaluation of [fn x] raises any exception, the name of the exception is printed on standard error output, and the programs aborts with exit code 2. Typical use is [Printexc.catch main ()], where [main], with type [unit->unit], is the entry point of a standalone program. This catches and reports any exception that escapes the program. *) val print: ('a -> 'b) -> 'a -> 'b (* Same as [catch], but re-raise the stray exception after printing it, instead of aborting the program. *) val to_string : exn -> string (* [Printexc.to_string e] returns a string representation of [e]. *)
