I wrote (with a little help) Dancer2::Plugin::LogReport for a
comprehensive and easy way to do this and a bunch of other stuff, whilst
keeping code to a minimum. I'm just about to post an article to the
mailing list about it.

I realise you're using Dancer1, but you might like to look at the
techniques involved, or even consider porting it to Dancer1 if it would
be of benefit to you.

That's exactly the idea behind the module - I got very bored writing
code similar to that in your examples.
