+Macros as pragmas
+~~~~~~~~~~~~~~~~~
+
+Whole routines (procs, iterators etc.) can also be passed to a template or 
+a macro via the pragma notation: 
+
+.. code-block:: nimrod
+  template m(s: stmt) = nil
+
+  proc p() {.m.} = nil
+
+This is a simple syntactic transformation into:
+
+.. code-block:: nimrod
+  template m(s: stmt) = nil
+
+  m:
+    proc p() = nil
