Redbean Lua and JSON serialization now goes faster because we're now
inserting object entries into tree data structure rather than making
an array and sorting it at the end. For example, when serializing an
object with 10,000 entries this goes twice as fast. However it still
goes slower than saying EncodeJson(x, {sorted=false}).
DESCRIPTION
Lua is a language designed for embedded use in native applications. It
has an impossibly elegant C API and the Lua language itself feels more
like Python compared to alternatives like Tcl except it's a great deal
faster and doesn't have strong opinions about character encoding.

commit e7803f7dbcdc966ab1f9db143424ee811ab1a398
Author: Roberto Ierusalimschy <roberto@inf.puc-rio.br>
Date: Wed Mar 3 09:44:20 2021 -0300
New release number (5.4.3)
luac.c needed to be sourced from:
https://www.lua.org/ftp/lua-5.4.3.tar.gz
LOCAL MODIFICATIONS
Lua now uses a bestline REPL with bash-style code completion.
Integer literals such as `033` will now be interpreted as octal.
Integer literals such as `0b10` will now be interpreted as binary.
The `\e` string literal escape sequence has been added, which is
equivalent to `\27` (the Lua version of `\033`) or the ASCII ESC
character. It may be used for teletypewriter control like having
bold text, which can be encoded elegantly as `\e[1mHELLO\e[0m`.
Added luaL_traceback2() for function parameters in traceback.
Added Python-like printf modulus operator for strings.
Added Python-like printf multiply operator for strings.
