With respect, I find Lua not such a good language for writing DSLs.
Haskell is a very good language for writing DSLs; compared to Haskell,
I find Lua barely adequate for these sorts of experiments.

I use Lua lots for all sorts of other things, but I really miss
Haskell's lightweight syntax for function definition, function
application, and infix operators---plus the power of lazy evaluation.
And I miss Haskell's type system!  When you start designing languages,
a type system can be enormously helpful.  Unfortunately, retrofitting
some static typing onto Lua's existing design turns out to be a hard
problem.
