While I’ve rallied against painting all code with final in Java, and have accepted that it’s handy to have const in JavaScript as it generally forces some discipline into free-for-all code, there’s an underlying rule which could be used to make me want more constants everywhere.

And the bigger the codebase ...

You can create a patch of your modified working state using git diff. The diff output is in the correct patch format. $> git status ...

You most probably know about Elegant Objects (EO), an alternative object-oriented paradigm, which claims that objects must be immutable, have no static methods, never use NULL in their code, use no annotations, and so on. We, the EO adepts, claim many things, but not so many people believe us. Those non-believers say that we are trolls, at best. Their main ...
