Use DATABASE_URL by default with Sinatra/Sequel extension

The README for sinatra/sequel states that the

set :database
statement can be omitted and it will use the
environment variable by default. Looking at the source, this appears to be true. However, omitting this line causes the following error when it tries to load my model definitions:

in `db': No database associated with Sequel::Model: have you called Sequel.connect
or Sequel::Model.db= ? (Sequel::Error)

I realize I'm being a bit pedantic by wanting to omit this line (and not have to write
:set database, ENV['DATABASE_URL']
) but for the sake of learning is there a way to invoke the default behavior of this module? I asked the question over here as well. Thanks in advance.
