I looked into it at some point, but I forgot why I didn't continue with it. It was probably about the same time I was looking at CGI::Application::PSGI
for application unit testing purposes.
If I have an Apache stack available, I will usually go with CGI::Application with CGI::Application::Dispatch because it's easier to set up in that case. But if not, I'll go with Dancer2 and starman.
There are many alternatives out there. If you're not just merely curious, what need do you have for it that can't be satisfied elsewhere, in particular?
