lib/perl5i/1/Meta/Instance.pm and lib/perl5i/2/Meta/Instance.pm both use Digest::SHA1 for the sha1 checksum. Digest::SHA is part of the standard perl distribution since perl v5.9.3 so this reduces the number of external dependencies by one.
Would it be possible to have perl5i using Digest::SHA? Most of the functionality (except sha1_transform) of Digest::SHA1 is also provided by Digest::SHA. Switching from Digest::SHA1 to Digest::SHA should be in principle as easy as substituting the use of Digest::SHA1 with Digest::SHA.
Many thanks for consideration! Backgound behind this request is in , the Debian Perl Group would like to drop the package providing Digest::SHA1, since Digest::SHA in perl core since 5.9.3 provides a similar interface.
Less dependencies good. I don't think I realized one was core and one is not when it was written.
Approved. Do it.
Use core module Digest::SHA instead of Digest::SHA1
Use the core Digest::SHA instead of Digest::SHA1.
Eliminate a CPAN dependency. We don't need the rest of Digest::SHA1 yet.
