I had noticed this from the latest devel on github - I should probably
add in a good error message for catching the old style of request
instantiation.

I would try adding an appname to these codereferences:

  set appname => 'foo'; # Or similar

If I recall correctly, the current app is stored by name, and with
these both being unnamed they will clobber each other. I have multiple
webapps working happily on the same Starman server, and they do not
interfere with each other.
