Config files in Ruby instead of YAML

Instead of requiring YAML for configuration, perhaps configuration could be done in Ruby too, much like Merb. For example, instead of the standard YAML config:

## config/config.yml

allow_from: all

logging:
  type: Logger
  level: debug

change to:

## config/init.rb

Halcyon.config.use do |c|
  
  # = Framework
  c[:allow_from] = :all
  
  # = Logging
  c[:logging] = {
    :type => 'Logger',
    :level => 'debug'
  }
  
  # = Application
  
end
