Minifiers join a derived constructor's statements into one comma expression (`super(message, options), this.name = ..., ...;`), which jose 6.2.12 ships in its error classes. The statement lowering already runs each operand of a statement-level comma as its own statement, so super() is accepted when only parentheses and comma operators separate it from its expression statement. Every other expression position keeps the SC1090 refusal. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
