You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: support.rb
    path of file: ./repos/fabrication/lib/fabrication
    
    the code of the file until where you have to start completion: class Fabrication::Support

  class << self

    def fabricatable?(name)
      Fabrication.manager[name] || class_for(name)
    end

    def class_for(class_or_to_s)
      class_name = variable_name_to_class_name(class_or_to_s)
      constantize(class_name)
    rescue NameError => original_error
      raise Fabrication::UnfabricatableError.new(class_or_to_s, original_error)
    end

    def constantize(camel_cased_word)
      names = camel_cased_word.split('::')
      Object.const_get(camel_cased_word) if names.empty?
      names.shift if names.size > 1 &
    
    def constantize(camel_cased_word)
      names = camel_cased_word.split('::')
      Object.const_get(camel_cased_word) if names.empty?
      names.shift if names.size > 1 && names.first.empty?
      names.inject(Object) do |constant, name|
        if constant == Object
          constant.const_get(name)
        else
          candidate = constant.const_get(name)
          next candidate if constant.const_defined?(name, false)
          next candidate unless Object.const_defined?(name)
          constant = constant.ancestors.inject do |const, ancestor|
            break const    if ancestor == Object
            break ancestor if ancestor.const_defined?(name, false)
            const
          end
          constant.const_get(name, false)
        end
      end
