parentheses at the end perform the actual call. So in this case, the
function is not called and the ``value`` and ``gas`` settings are lost.
Function calls cause exceptions if the called contract does not exist (in the
sense that the account does not contain code) or if the called contract itself
Due to the fact that the EVM considers a call to a non-existing contract to
always succeed, Solidity uses the ``extcodesize`` opcode to check that
the contract that is about to be called actually exists (it contains code)
and causes an exception if it does not.
Function calls also cause exceptions if the called contract itself
throws an exception or goes out of gas.
