Change the default file handle use by `print` and `say` to STDERR. The
default file handle is use when no file handle is specified. Example:
print "Hello world\n";
This print will output to STDERR.

Set the auto-flush for the default file handle. Auto-flush means to
output everything that's in the file buffer after every `print` or
`say`.
