   To be sure that your contract can receive Ether in that way, check the gas requirements of the fallback function
   (for example in the "details" section in Remix).
 
 - There is a way to forward more gas to the receiving contract using
   ``addr.call.value(x)("")``. This is essentially the same as ``addr.transfer(x)``,
   only that it forwards all remaining gas and opens up the ability for the
