+Internally, Solidity performs a revert operation (instruction ``0xfd``) when a user-provided exception is thrown. In contrast, it performs an invalid operation
 (instruction ``0xfe``) if a runtime exception is encountered. In both cases, this causes
 the EVM to revert all changes made to the state. The reason for this is that there is no safe way to continue execution, because an expected effect
 did not occur. Because we want to retain the atomicity of transactions, the safest thing to do is to revert all changes and make the whole transaction

 In the above, "tightly packed" means that the arguments are concatenated without padding.
 This means that the following are all identical::
