I'm starting to use Vim for editing my Perl scripts and I found that any time I do something like 'yiw' it does not include the sigil.

For example

my $pet = "dog";
[download]

Putting cursor on 'p' and copying the word copies pet instead of $pet.

Is a good idea or should it be avoided?
I tried searching for vim word objects to include sigils but didn't find anyone else doing this or even how to update the vim config file.
