Replying to my own question, it seems the most "elegant" way of accomplishing this requires this to be done be in two stages:

- First, delete the blocks in question from the block list table, eg doc.blocks.
- Second, insert them into the same table using pandoc.Div().

Unfortunately it seems table.delete() does not accept a list of blocks, only one block at a time, pandoc.Div, on the other hand, accepts a table. Here is a code example when I was trying it out:

local temp = {}
for i = 3, 1, -1 do
  table.insert(temp, table.remove(doc.blocks, 5))
end

table.insert(doc.blocks, 2, pandoc.Div(temp))

The above code removes blocks 5 through 7 from doc.blocks, then inserts them, in the same order but surrounded by <div></div>, in position 2.

If there is a better way of accomplishing this, I would appreciate hearing it.
