The question in question: A platform-independent implementation of "which" in Ruby
The OP has rather specifically asked that people not talk about how to improve the readability of the code (which, to my eyes, is nearly opaque). He's convinced that his code has "correct logic structure", and "refusing to compromise it for the sake of readability is an option".
It's certainly an option when you're not posting questions about it. But offering such suggestions is basically what Code Review does.
If someone is preemptively and emphatically declaring that advice off limits...is the question still on topic?
