Thanks!

The new service framework makes this approach less important.

However, I'm not sure if we should change the standard documentation at the moment.

In other words, you can write:

# Previous way:
load :rack

rack "myhost" do ...

# Better way:
require "falcon/environment/rack"

service "myhost" do
 include Falcon::Environment::Rack
end

The reason why the latter is better, is because it doesn't require to use falcon host to start, async-service can start it too, and it can be combined with other services, e.g. background job runner, etc.

Ah, interesting! I was just fixing the docs as I encountered them today, but indeed that seems less magical.

My original thinking behind "load ..." was that it would be less "falcon specific". But it turned out not to be useful and probably harmful.
