jameysharp opened PR #5233 from isle-fix-iflet to main:

The is_root flag to translate_pattern just determines whether the rule_term argument is used, which begs a larger cleanup. But that cleanup is less clear if is_root is set anywhere aside from the call in collect_rules. So I wanted to get confirmation that this particular use of that flag is incorrect first.

These two arguments (is_root and rule_term) are used to prevent expansion of a term as an internal extractor ("macro") if:

• that term is also an internal constructor
• and it's the root term on the left-hand side of the current rule
• and the pattern we're currently translating has no parents.

I'm not sure what it should mean to use the term you're currently defining as the root pattern on the left-hand side of an if-let in the same rule, but I don't think it should have this particular special treatment.
