dbrady / private_class_method.rb
Created November 22, 2017 16:22
Best idiom for private class methods nowadays, i.e in Ruby >= 2.1 and/or for values of "nowadays" significantly greater than 2014?

# Names of classes and methods have been changed to protect the innocent. Namely
# my sweet, innocent, cherubic, and hopefully continuing, employment.

# Okay, so: say I want to make a class method private. What's the best idiom
# for doing this in Ruby circa 2017?
# In Ruby 2.0 I can do Options 1 or 2:
# Option 1 - Original Flavor, Most Explicit

Which method of declaring a private class method feels most idiomatic now?

EDIT: Was gonna tweetstorm this, then decided to just gist it. Enjoy. ;-)
Tweetstorm about deceptive code incoming.
First Point: People believe comments over the code, even if the code is obvious: x=1; /* put 2 in x */ <-- people believe the 2
Second Point: People maintain code without maintaining (or sometimes even reading) the comments for that code
Third Point: Programmers love to optimize. Makes us feel smart. We think it makes us LOOK smart. But that way lies madness...
So. Dateline: Salt Lake City, 2002. I find this piece of assembly code: "XOR EAX, EAX ; PUT 1 IN EAX"
XOR any number with itself, you get 0. So the comment here was wrong, but if you don't know the XOR trick, it's outright deceptive
If you DO know the trick, it's still distracting and makes you stop and question your sanity for a moment
So I tracked down the commit history for the commit, and here's what happened (exit tweetstorm here if you don't want full history)
