daemon/engine: syntactic sugar for module ‘get’, ‘set’ properties
if the module declares such properties, they can be accessed
by treating module as a table, e.g.
hints[‘localhost’] = ‘127.0.0.1’
hints.hostname = ‘192.168.1.1.
print(hints.localhost)
equals to:
hints.set(‘localhost 127.0.0.1’)
hints.set(‘hostname 192.168.1.1’)
print(hints.get(‘localhost’))
