Sure it does, if I widen my previous code a little:
//using try/catch
try {
val handle = fileOpen(fileName)
doSomethingWithFile(handle)
} catch {
case FileNotFoundException(e) => ...
case IOException(e) => ...
case Exception(e) => ...
case throwable(e) => ...
}
Easier syntax, full pattern matching and usable on any stack frame. But
absolutely no checked exceptions.
