I say no. Furthermore, I'll be so bold as to say that few applications truly require persistence at all.

Here's a cool URL mapper for Plack apps. It works great for Plack apps but it fails to pull in more than the first Mojo app. I have no idea why but load_psgi (`do "$filename"`) must work differently after the first Mojo app is loaded. Error: "Can't use string ("Mojolicious::Commands") as a subroutine ref while "strict refs" in use at /usr/share/perl5/vendor_perl/Plack/Middleware/Auth/Basic.pm line 30."
