So [...] having written their expression, [...] having to guess whether it contains an EOD or not.
So, don't do that.
Don't what? Write expressions?
You have to write expressions, you cannot write code without doing so.
Or maybe you mean don't guess? That's what I'm advocating. If the order of execution is defined, I do not have to guess.
Without that, there is no choice.
One example does not a comprehensive list make.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco.
Rule 1 has a caveat! -- Who broke the cabal?
