Oh. I see what the complaint is about and why it disappears! Take a look at these two lines of code:

our @EXPORT_OK = qw/&greet/;
our $VERSION = '0.1';
[download]

The assignment operators (=) don't line up. When perltidy adds the spaces, it's creating whitespace that aligns those operators.

our @EXPORT_OK = qw/&greet/;
our $VERSION   = '0.1';
[download]

Now the the code is tidy and the assignment operators are aligned, perlcritic stops complaining.
