Looks like we posted at the same time.
I see that you have created a new array type. My approach in Ravi is
to create sub types of Table (similar to how Integer sub type of
Number works). Having a separate type does have some advantages - one
can optimize the structure for arrays, for example.
BTW you also need to update all the Lua api functions so that they
work transparently on arrays.
