Please consider renaming public to public_dir as it hides the public method in Module

[Kris Selden]

I'm trying to decorate the error method as follows:

alias_method_chain :error, :formatting

but this is failing here:

def alias_method_chain(target, feature)
...
case
when public_method_defined?(without_method)

public target
...
end

because of:

set :public, Proc.new { root && File.join(root, 'public') }
