There are many things that would be better done using a dynamic scripting language rather than TeX macros. But you still need to make binaries so that at the command line a user can type: latex3 <myfile> (Particularly on Windows, you can't assume *any* scripting languages will be available "just like that". That is one reason Lua is a possible in the longer term: if LuaTeX is installed, you can always just use the Lua part without the TeX.) -- Joseph Wright
