Follow-up from PR review: nested if is the right answer for two or three dependent conditions, but past that the nesting becomes the problem. AL's case statement is the flat alternative — the control statements documentation states a value set "must be an expression or a range" and that the first matching value set executes, so case true of / case false of accept boolean expressions and stop at the first match. That is the laziness the boolean operators do not provide. Adds case-true-of-for-long-condition-chains.md with good/bad AL companions: case false of for guard chains where every condition must hold, case true of for first-match dispatch. The bad sample shows both failure shapes — a five-level if ladder, and the worse escape of collapsing it into an and chain, which trades nesting for a real defect. Cross-links both articles, and adds the threshold to the short-circuit article's Best Practice so following it does not lead to a deep ladder. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |
