Can embedding Lisp-like code?

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

Not strongly typed

Info box says in "Typing discipline", "strong", but that is not true.

Similar to PHP or JavaScript, (and probably Perl and AWK), Lua has is weakly typed especially in arithmetic, i.e. "10" + 1 is allowed and result is integer 11 (technically number 11.0). Same with "5.5" * "2", is integer 11. On the other hand indexing into a "array" (table), t["1"] and t[1] are different (but t[0+"1"] and t[1] are same).

Some people argue that that is still strong typing, because for string concatenation one would use ".." in Lua. But that is not good enough argument. For example Wikipedia says C is weakly typed, but arguably Lua has even weaker type system, due to above mentioned value coercion in arithmetic, which does not happen in C. 81.6.34.169 (talk) 01:32, 1 September 2024 (UTC)

Problems with "Inheritance" section

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)

• Lua (programming language) → Lua
• Lua → Lua (disambiguation)

– Lua (programming language) is clearly the WP:PRIMARYTOPIC. 2600:1700:6180:6290:E1BC:304B:79DF:C9EB (talk) 19:43, 4 April 2025 (UTC)

• Support I agree, Lua (programming language) is certainly the primary topic here.

• Strong Support the name Lua is more familiar with the programming language than others._saluere, Ɔþʱʏɾɪʊs^⚔ 09:59, 11 April 2025 (UTC)
