hash['key'] to hash.key in Ruby

Question

I have a a hash

foo = {'bar'=>'baz'} 

I would like to call foo.bar #=> 'baz'

My motivation is rewriting an activerecord query into a raw sql query (using Model#find_by_sql). This returns a hash with the SELECT clause values as keys. However, my existing code relies on object.method dot notation. I'd like to do minimal code rewrite. Thanks.

Edit: it appears Lua has this feature:

point = { x = 10, y = 20 }   -- Create new table print(point["x"])            -- Prints 10 print(point.x)               -- Has exactly the same meaning as line above
