-- haxe-parity Task 2 review fix (Important): a genuine sub-parse
-- failure inside "${...}" (`1 +`, not just trailing garbage) must
-- report at this string literal's own position with the malformed-
-- interpolation message -- not at the sub-lexer's own uncorrected
-- line/col (which used to land on some unrelated line of this real
-- file). See compiler/test/runner.ml's direct assertion for the exact
-- position/message pin; this fixture only pins the outcome (WO-E101).
