I don't see Enumerable here:

$ ruby -e 'p ObjectSpace.ancestors'
[ObjectSpace]

> ObjectSpace.enum_for(:each_object)

Doesn't work as presented:

$ ruby -e 'ObjectSpace.enum_for :each_object'
-e:1: undefined method `enum_for' for ObjectSpace:Module (NoMethodError)

Remembering that enum_for is the thing you want and which library to  
get it from is the annoyance factor.

This usually is enough to discourage people.
