    Opcodes `returndatacopy`, `returndatasize` and `staticcall` are available in assembly.
    The `staticcall` opcode is used when calling non-library view or pure functions, which prevents the functions from modifying state at the EVM level, i.e., even applies when you use invalid type conversions.
    It is possible to access dynamic data returned from function calls.
    revert opcode introduced, which means that `revert()` will not waste gas.
