Because of course ternary operators would cause problems. The two problem: LFS_ASSERT((exists) ? !err : err == LFS_ERR_NOENT); lfsr_file_sync(&lfs, &file) => (zombie) ? 0 : LFS_ERR_NOENT; We could work around these with parentheses, but with different assert parsers floating around this issue is likely to crop up again in the future. Fortunately this just required separate "sep" vs "term" rules and a bit more strict parsing.
