A problem is here though. If we hit the end > current clause, then we need to make i < end inclusive, to get current too. Or set end = current +1.

start = 1, count = 2, current = 100: should lead to [1, 2]
start =1, count=100, current = 2, should lead to [1,2]

block := api.eth.BlockChain().GetBlockByNumber(i)
bodies = append(bodies, getBody(block))
body := getBody(block)

Hmm, it's wrong. The returned body can be nil, isn't it?

That's fine, we want a nil entry in the slice in that case (right?)

But the deref in line 789 should panic then, no?
I don't understand why we need to make the result an array not an array of pointers

it was a shot-in-the-dark attempt at a fix. prob should have moved the PR back to draft at that point.

bodies = append(bodies, *body)

return bodies, nil
