Thanks @hseg — your rebase of postmanlabs#646 is carried forward in #66, with a regression test added (compiles every package module with escape-sequence warnings escalated to errors). I confirmed the raw-string conversion leaves the ASCII art and the regex behaviour byte-for-byte unchanged. You're credited as co-author. Closing in favor of #66. |

The two ASCII-art literals and the parse_multi_value_header() regex used unrecognized escape sequences (\_, \ , \s), which emit a SyntaxWarning on Python 3.12+ (DeprecationWarning earlier) and will become a SyntaxError in a future Python. Make them raw strings; the rendered art and regex behaviour are byte-for-byte unchanged (verified against the prior values). Adds a regression test that compiles every module in the httpbin package with escape-sequence warnings escalated to errors. Closes psf#62. Supersedes psf#55. Co-Authored-By: gesh <gesh@gesh.uni.cx>
