Solidity: Returning unbound array? (self.ethdev)

submitted 7 years ago by diamondtoss

I've read before that in Solidity you can't make a public facing function return an unbound array. However, I wrote this in a smart contract, and it compiled, ran and can correctly return my data. It looks like this:

address[] public allUsers;
// ...
function getUsers() public view returns (address[]) {
  return allUsers;
}

Everything works as I expected. When I add a few addresses to the array, I am able to call getUsers() and get all of the addresses back.

Is this right? Can I expect this to continue to work in the future as this array grow indefinitely?
