Anchor: variable number of accounts in instruction wrapper

Question

How can one set a variable number of input accounts for a an instruction wrapper?

ie given this:

#[derive(Accounts)]
pub struct Initialize<'info> {
   ...I'd like to specify here a random number of accounts
}

This is useful when you would want to refer to all creators of a digital asset (say NFT), but you don't know in advance how many there are.

Oh, I have just found out you can use something like this:

pub fn do_something(ctx: Context<Initialize>) -> ProgramResult {
    let vec: Vec<AccountInfo> = ctx.remaining_accounts.into_vec();

    // do something with the accounts

    Ok(())
}
