  "message": "Optimize hex parsing. (#520)\n\n* Optimize hex parsing.\n\nThe biggest improvement comes from using a `const` string as table. That avoids (potentially) a lazy initialization check on accessing the `_charFlags`. Also, a constant string may have a fixed location in memory.\n\nNegating the \"is valid hex\" and putting the bit in bit 7 allows using `entry.toSigned(8)`, which a smart compiler should be able to turn into a single sign-extending opcode.\n(Using `(entry \u0026 0x0F) - (entry \u0026 0x80)` works too.)\n\nThe `missing_whitespace_between_adjacent_strings` lint doesn\u0027t understand that not all strings are text.\nMaybe it shouldn\u0027t trigger for strings containing character escapes.",
