I have been reading the documentation for Getopt::Long but I can't find a way to do what I would like to achive.

Let's restrict it to one option only: verbose. What I would like is to be able to use -v or --verbose only. So -verbose and --verb would both be wrong.

The main code is:

use Getopt::Long;
my $verbose='';
GetOptions ( 'verbose' => \$verbose );

[download]

However, that accepts -V also. So I change it to

use Getopt::Long qw{:config no_ignore_case};

[download]

So far so good, but now --v or -ver both work. I thought I could use bundling like 

use Getopt::Long qw{:config bundling no_ignore_case};

[download]

but it doesn't quite do what I had in mind.

If I use -ver it correctly says

Unknown option: e
Unknown option: r

[download]

But if I use --verb (note the double dash) it still recongnises it, which I don't want.

To summarize: if there is one dash then only v is accepted and any other letter should be reported as an 'Unknown option'; if there are two dashes then only the full 'verbose' should be accepted. How can I achive that?

Thanks
