# Builder::BlankSlate class.

# Ruby 1.9 introduces BasicObject which differs slightly from Builder's
|
|
# BlankSlate that has been used so far. ActiveSupport::BasicObject provides a

# barebones base class that emulates Builder::BlankSlate while still relying on
|
|
# Ruby 1.9's BasicObject in Ruby 1.9.
