It seems from examples that appname must be a package (specifically, a package which uses Dancer2) but I don't think it's spelled out anywhere that this is a requirement (I've looked in Manual and Manual::Migration). I notice that Dancer2::Plugin seems to depend on this - https://github.com/PerlDancer/Dancer2/blob/c598c4c45db729ba9e8a9af79a0afcb3a... . Could you confirm this is the intention and that arbitrary app names are not permitted? Happy to write a docs patch to make it clearer if so.
