Re^2: Getopt::Long good style?

I didn't understand the "hashy" part of GetOpt::Long yet, but it sounds good to me.

Regarding the

'h|help'   => sub { help() },
[download]

part, I don't get the point. What's the advantage over:

'h|help'   => \&help,
[download]

That way is fine also. I tend to shy away from &'s in general out of personal preference. I just like... `'h\|help' => sub { help() }, ... sub help { ... }` [download] better than... `'h\|help' => \&help, ... my $help = sub { ... }` [download] -- "A long habit of not thinking a thing wrong, gives it a superficial appearance of being right." -- Thomas Paine naChoZ	[reply] [d/l] [select]
