Smalltalk - Conditional Compilation

Created on 2020-08-27T01:56:34.458484

Smalltalk/X allows marking a method as "ignored" so it appears in class browsers, but otherwise generates nops when called.
Maintaining code for multiple Smalltalk dialects is annoying because there is no standard way to keep the code together for all of them, yet only run the code meant for the current one.
