Hey Greg,

I hope it's not too late to chime in.

Sounds good.

The way I suggest people write their website is by separating the
application logic from the web layer. I usually implement an API with
routes defined under MyApp/Web.pm. The rest of MyApp/ contains all the
application logic that can survive and live without the web layer, if needs

In your case, writing just the web layer would be very simple. You could
then transition it to your use application, written in whatever language
you want. If you write it correctly, you could switch from Dancer to a
different web framework (whether in Perl or not).

Hope that helps, and good luck with your endeavor! :)
