Yeah, but that doesn't extend to match { let f = fopen(); fwrite("aha", f); fclose(f); } { Err(e) => println("either of fopen, fwrite or fclose fai

Yeah, but that doesn't extend to match { let f = fopen(); fwrite("aha", f); fclose(f); } { Err(e) => println("either of fopen, fwrite or fclose failed"), _ => () } without something like a try! variant that breaks out of a block instead of returning from a function on error.
