I find it quite likely that you are using singletons a lot. I'd say 
that
in Ruby, constants are pretty much scoped global variables.

Note that I'm not saying this is necessarily bad; I just mean that 
there's
not much difference between "singletons" and "global variables". Both
represent global state, and the global state itself should be regarded 
as
possibly harmful, not particular manifestations of it.
