I was interested to read about Wren in "Scripting Languages You May Not Know" at http://news.dice.com/2015/01/13/scripting-languages-may-know/ . A search for "Wren" on http://lua-users.org/wiki/ did not reveal anything. There appear to be quite a number of Lua-based or Lua-inspired languages developed by individuals. I take them to be a tribute to Lua and the clarity of its source code. Presumably they vary from the tentative experiment to the fully-tested. Should their authors be invited to describe their creations in a dedicated section of the Wiki? -- Gavin Wraith (gavin@wra1th.plus.com) Home page: http://www.wra1th.plus.com/
