I like the scaffolding idea. I try many different tools and techniques. Scaffolding enables me to look at more alternatives by saving time.

The challenge to getting scaffolding to work in a Perl environment is that there are so many dependencies. An interesting test is to start with a bare-bones perl build, get the cpan module configured, and type 'install Catalyst::Example::InstantCRUD'. When I tried this (linux FC3, perl-5.8.8), the build proceeds for quite a while, and then fails with:

Failed during this command:
  ISLUE/Catalyst-Plugin-Session-State-Cookie-0.05.tar.gz: signature_verify NO
  TKP/DBIx-Class-DigestColumns-0.02000.tar.gz  : make_test NO

I would contrast this with Ruby on Rails, which installed and operated without errors when I tried it. I really like the concept, but a scaffold is only as stable as the ground underneath it. I think that keeping the underlying Catalyst modules working will be the major challenge to the possible role of InstantCRUD in getting new users to try Catalyst.
