Not necessarily. It can be done with scalars as easily as with hashes
and, in fact, I do it like that quite often.
Try this instead:
our $opt_h;
getopt('h);
That satisfies both the strict pragma and the desire to use a scalar
varaible for your command line option.
That's interesting. What if I have multiple options and still want to use
scalars?
Would I use multiple calls to getopt for each scalar, or could I pass them
all to a single call to getopt?
