Ruby question: In preparation to a Rails 7 upgrade I am currently rewriting some monkey patches from

Module.module_eval

into

Module#prepend

. So they work with the new zeitwerk auto loader. [Due to a "bug" in Ruby 2.7](https://github.com/jruby/jruby/issues/6445#issuecomment-894407106) prepended modules of modules included in classes do not get prepended to the class, leading to not overwritten methods as one would expect using

Module#prepend

with modules prepended into classes. I have several ideas to circumvent the issue 1. Prepend the module into the class the module that the monkey patch was meant for. Problem with this is that the module in question (

Spree::Core::ControllerHelpers::Order

) is included in several controllers and I would like to not maintain a list of controllers that I need to prepend my module in to. 2. Use

module_eval

in the

prepended

hook. Just an idea I have, that I have not tried yet. 3. Trick Zeitwerk by adding the constant it expects from the file name and keep the existing

module_eval

Feels fishy 4. Use a folder that is excluded from Zeitwerk auto loading. Not very convenient during development locally. Has anybody run into these kind of issues before and solved it? If yes, how?
