+Stropping
+---------
+
+`Stropping <https://en.wikipedia.org/wiki/Stropping_(syntax)>`_
+allows the same letter sequence to be used both as a keyword and as an identifier, and simplifies parsing.
+For example, allowing a variable named `if` without clashing with the keyword `if`.
+In Nim, this is achieved via backticks, allowing any reserved word to be used as an identifier.

+Examples

+.. code-block:: nim

+  `int`: int

+  let `object` = Type(`int`: 9)
