r = Redis.new(options)

# classic:
r.set('foo', 'bar')
r.get('foo')
r.sadd('baz', 1)
# etc.

# this could be cool:
k1 = r.key('foo')
k1.set('bar')
k1.get
k2 = r.key('baz')
k2.sadd(1)

# or even typed:
k1 = r.key('foo') # defaults to string
# ... as before
k2 = r.key('baz', 'set')
k2.add(1) # since it's a set, sadd could just become add
