# Problems:
#
# - Want to be able to have functions in the main file also,
#   so it has to be a class.
# - Should it be possible to pass around the Main object?
# - Should it be possible to support event-driven flows?
#   e.g. for GUI programs, or for phone apps (that can be stopped/
#   started by decisions by the OS), or for services (also start/stop),
#   or for socket-activated stuff (could allow multiple activations
#   per instance/process), or FastCGI, etc...
#
# Should the main file be:
#    1. a special case
#    2. an external extension of an abstract class
#    3. a standard class that has a `main` method that takes some
#       parameter with the main class?
#    4. a standard class that has a `start` method that takes the
#       main class (and e.g. stores it in an instance variable),
#       plus "event" methods? or the possibility to register events?
