This can be combined with the compiler transform plugins of Opal:
-> make subclass of OCCompilerASTPlugin
-> put your code in a method called #transform
now when you override #compiler on the class side of a class like this:
compiler
^super compiler addPlugin: ASTPluginMeaningOfLife.
the plugin will be active for the hierarchy, which means that all code compiled
will be transformed.
There is a simple example ASTPluginMeaningOfLife in the image.
