On 4 April 2025, it was proposed that this article be moved from Lua (programming language) to Lua. The result of the discussion was moved.

e.g.:

  quote(string)                     -> "string"
  quote(quote(expr))                -> "quote(expr)"
  quote(quasiquote(expr))           -> "quasiquote(expr)"
  quote(quasiquote(unquote(expr)))  -> "quasiquote(unquote(expr))"
  quote(unquote(expr))              -> "unquote(expr)"
  quasiquote(string)                -> "string"
  quasiquote(quote(expr))           -> "quote(expr)"
  quasiquote(quasiquote(expr))      -> "quasiquote(expr)"
  quasiquote(unquote(expr))         -> expr

Seems to imply Lua was created for political reasosn but no proof is provided.

"From 1977 until 1992, Brazil had a policy of strong trade barriers (called a market reserve) for computer hardware and software, believing that Brazil could and should produce its own hardware and software. In that climate, Tecgraf's clients could not afford, either politically or financially, to buy customized software from abroad; under the market reserve, clients would have to go through a complex bureaucratic process to prove their needs couldn't be met by Brazilian companies. Those reasons led Tecgraf to implement the basic tools it needed from scratch.[5]" — Preceding unsigned comment added by ~2026-12627-08 (talk) 21:42, 25 February 2026 (UTC)Reply

Truth is the restrictions on imports finished one year prior.

The "Inheritance" subcategory in the article is written and phrased in a way that could easily lead a reader to believe believe features such as multiple inheritance are features built into the Lua language. However, the technique is a pattern implemented using metatables, not a language feature.

While the "Object-oriented programming" category above does indeed explain that Lua doesn't have a built-in concept of classes, the addition of the class inheritance section below it seems to deviate from that tone, and it describes a niche pattern that is rarely used; it feels like somebody wrote their own little pet program in Lua and added it to the article masquerading as a feature. 24.68.84.200 (talk) 07:17, 29 September 2024 (UTC)Reply
