+ -- | GHC note: a 'Handle' will be automatically closed when the garbage
+ -- collector detects that it has become unreferenced by the program.
+ -- However, relying on this behaviour is not generally recommended:
+ -- the garbage collector is unpredictable. If possible, use
+ -- an explicit 'hClose' to close 'Handle's when they are no longer
+ -- required. GHC does not currently attempt to free up file
+ -- descriptors when they have run out, it is your responsibility to
+ -- ensure that this doesn't happen.
