 Notations
 ---------
 
-The signatures of most objects can be written using a succinct DSL for Coq notations (think regular expressions written with a Lispy syntax).  A typical signature might look like ``Hint Extern @num {? @pattern} => @tactic``, which means that the ``Hint Extern`` command takes a number (``num``), followed by an optional pattern, and a mandatory tactic.  The language has the following constructs (the full grammar is in `TacticNotations.g <doc/tools/coqrst/notations/TacticNotations.g>`_):

 Tips and tricks
 ===============
 
+Nested lemmas
+-------------
+
+The ``.. coqtop::`` directive does *not* reset Coq after running its contents.  That is, the following will create two nested lemmas::
+
+   .. coqtop:: all
+
+      Lemma l1: 1 + 1 = 2.
+
+   .. coqtop:: all
+
+      Lemma l2: 2 + 2 <> 1.
+
+Add either ``undo`` to the first block or ``reset`` to the second block to avoid nesting lemmas.

 Abbreviations and macros
 ------------------------
 
-Abbreviations and placeholders for specially-formatted names (like ``|Cic|``, ``|Coq|``, ``|CoqIDE|``, and ``|Gallina|``) are defined in a `separate file <doc/sphinx/replaces.rst>`_ included by most chapters of the manual.  Some useful LaTeX macros (like ``\alors``), are defined in `<doc/sphinx/replaces.rst>`_.
