[, opts = {}]

Shouldn't we just use [, iterator={iterator_type}] instead?

please double-check with @Totktonada

Why not to check it myself?

box.cfg{}
box.schema.create_space('s')
box.space.s:create_index('pk')
box.space.s:insert({1})
box.space.s:insert({2})
box.space.s:insert({3})
for _, tuple in box.space.s:pairs(nil, {iterator = box.index.REQ}) do print(require('json').encode(tuple)) end
for _, tuple in box.space.s:pairs(nil, {iterator = 'REQ'}) do print(require('json').encode(tuple)) end
for _, tuple in box.space.s:pairs(nil, box.index.REQ) do print(require('json').encode(tuple)) end
for _, tuple in box.space.s:pairs(nil, 'REQ') do print(require('json').encode(tuple)) end

Thanks for the feedback and examples. Variant №3 seems to cause error. Since №1 and 2 are working well i think it will be best to change the documentation to [, iterator={iterator_type}] syntax instead of [, iterator-type].
