+Non-standard Packed Mode
+========================
+
+Solidity supports a non-standard packed mode where:
+
+- no :ref:`function selector <abi_function_selector>` is encoded,
+- short types are not zero padded and
+- dynamic types are encoded in-place and without the length.
+
+As an example encoding ``uint1, bytes1, uint8, string`` with values ``1, 0x42, 0x2424, "Hello, world!"`` results in ::
+
+    0x0142242448656c6c6f2c20776f726c6421
+      ^^                                 uint1(1)
+        ^^                               bytes1(0x42)
+          ^^^^                           uint8(0x2424)
+              ^^^^^^^^^^^^^^^^^^^^^^^^^^ string("Hello, world!") without a length field
