53/// ANTLR's runtime-testsuite descriptors byte-compare output produced by
54/// Java's list rendering (`getRuleInvocationStack()`, token-getter lists).
55/// Rust's `Vec` `Debug` quotes elements, so — like Go's
56/// `antlr.PrintArrayJavaStyle` and Python's `str_list` — the Rust target
57/// exposes a dedicated formatter for generated test actions.
