Hi, Grape::DSL::Helpers::ClassMethods#helpers evaluates helper methods in context of a given helper module, that leads to problems if that helper module is used anywhere else.

Example

helpers MyHelperModule do
  def resource
    ...
  end
end

now if I include MyHelperModule anywhere else, I'll have resource method, that I don't want to include
