Another approach would be to distribute a version of Lua that was
specifically designed for command line consumption. Which is only a
lot bit close to the whole "Batteries" thread.
There is a line between "Embedded Scripting Language" and what PERL
is. Adding thoughtful hints like this makes even more sense, when
there is a reasonable library, package manager, etc.
Since Lua's REPL is mostly useful when developing Lua applications, it
seems like its terse and "documented only just enough" approach is
consistent with the rest of Lua.
An enhanced and possibly more verbose repl seems like a great fit for LuaDIST.
