|

Macros are useful when one wishes to extend the Hy or write their own
|
||||
language on top of that. Many features of Hy are macros, like ``when``,
|
||||
``cond`` and ``->``.
|
||||
|
||||
To use macros defined in a different module, it is not enough to
|
||||
``import`` the module, because importing happens at run-time, while we
|
||||
would need macros at compile-time. Instead of importing the module
|
||||
with macros, it must be ``require``d:
|

|

.. code-block:: clj

=> (require tutorial.macros)
