Ruby: alias_method conflicting with prepend

alias_method makes a copy of a method. This works fine until the same method is overridden using prepend. If the prepend is executed after alias_method, you'll either see an infinite loop, or loose the prepended functionality.

Solution

Your options are:

• Ensure prepend happens before alias_method
• If you can control the alias_method invocation: rewrite to the modern & better prepend
• If you can only control the prepend invocation: rewrite to the legacy alias_method
