I had already looked at Dancer myself. As a result, you can see these
entries in the Dancer ChangeLog:

    * Security Fix: protection from CRLF injection in 
      response headers (thanks to Mark Stosberg for the report).
    * Support for multi-valued params in GET/POST data (thanks to
      Mark Stosberg for the report).

So, in a short review, I found that it lacked support for multi-valued
params, and that it had a notable security hole. If you look into it
deeper, what else might you find?

I think it has some nice points, too, but it's not worth switching to
something so new from something proven from years of use to be stable
and reliable.
