Re: [WikiEN-l] MediaWiki is getting a new programming language

Hi!
Is there any progress on this? Or, that's closed topic and such built-in
language won't be implemented?
By the way, the lots of MediaWiki installations use TeX, so OCaml is
already available as the language for extensions. Imagine #ocaml parser
function or an ocaml tag. It's not the most lightweight choise, though.
Also, Bryan Tong Minh had a great idea - choosing between an external
(compiled) version of Lua (or another scripting language) and
"fallback" to slow built-in interpreter, when the first choice is
unavailable. Perhaps a limited subset of Lua.

It's possible to preprocess the source first, to "filter out" the extra
language constructions which are not supported by built-in interpreter.
Throw an error in such case.
Anyway, maybe Victor Vasiliev will present a different language.

It will be broken only if some extra non-supported language
constructions are presented in the source text. One syntax check
pre-processor for both paths: PHP interpreter and external interpreter.
