You probably want to move this to the end of the file. Perhaps before the last OK print and maybe add a print saying you are testing the pretty printer.

Another option is to add the pretty printer test code at the end of this test file.

Calling the documented
pp.tostringAPI on an AST containing a string assigns each byte to the globalchar, overwriting a caller's existing value or creating a new global.Make the loop variable local. The standalone pretty-printer regression checks existing and absent global values; as requested in review,
test.luanow runs it near the end, announces the section, and keeps its shebang first.Validation: the earlier revision's isolated embedded Lua 5.1, 5.3 and 5.4 regression passed. For the current revision,
git diff --checkpassed; native Lua and LPegLabel are unavailable here, so the full suite and runtime matrix remain unverified.
