Why does ary.each unload the entire contents of an object?

foo is an array of objects, bar is an attribute of this object.

(rdb:1) foo.bar.map{|v| bar.v }
["a", "b", "c", "d", "e", "f"]


(rdb:1) foo.bar.each{|v| p bar.v }

foo.bar.each{|v| p bar.v }; nil

You can simply click .any?at the end of the expression:

(rdb:1) foo.bar.each{|v| p bar.v }.any?
# output from only the #p call
=> true
