Agreed!

That all raises the question whether Lua should support
some minimal form of domain specific language, probably
via including token filter into the std. distribution.
That would reduce the need to build a complete language
on top of Lua.

Of course, this would require to implement one more policy
into Lua, something like
domain(GSL)
    ...
