There is "Short Anonymous Function" syntax page
(http://lua-users.org/wiki/ShortAnonymousFunctions), which includes
"do end" power patch for functions
(http://lua-users.org/wiki/LuaPowerPatches) and short anonymous
function syntax (http://lua-users.org/wiki/LuaPowerPatches), like
|param| param + 2. The latter is also implemented by GSL shell
(https://github.com/franko/gsl-shell) and LuaJIT lang toolkit
(https://github.com/franko/luajit-lang-toolkit).
