Careful: lua_tostring has side-effects[1] (perhaps the name of this
function is misleading).  It's also more correct to do
"if(lua_toboolean(lstack,i) != 0)" .

Was my first thought too... but perhaps cleverly accidently he checks that it isn't a number before checking if it's a string. So side effect free :)
Must say though stack watches are brilliant for working with the lua stack, although writing a good table printer without side effects/recursion problems is hard.
