While I do like me some good meta-reasoning, at least I have an argument for shorter function names:
Short names are read in O(1) while longer are O(n) (unless the name can be simplified as “the function with the long name”)
> me like metareason, me have arg for short func name: Short name O(1), long are O(n) (some name too long: “the function with the long name”)
There's where your logic breaks down. If you truly followed the O(N) argument for all your communication mediums outside of programming you'd sound not so intelligent. Likely you built this argument as a response rather then actually followed it in both your English and programming communication styles.
Better re-examine that meta-reasoning.
