      <dt><b><a name="arity">arity</a>:</b> The number of arguments accepted
      by a function or member function. Unless otherwise specified, the
      hidden "<code>this</code>" argument to member functions is not counted
      when specifying arity</dt>

      <dt><b><a name="ntbs">ntbs</a>:</b> Null-Terminated Byte String, or
      `C'-string. C++ string literals are <strong>ntbs</strong>es. An
      <strong>ntbs</strong> must never be null.</dt>

      <dt><b><a name="raise">raise</a>:</b> Exceptions in Python are
      "raised", not "thrown", as they are in C++. When this documentation
      says that some Python exception is "raised" in the context of C++ code,
      it means that the corresponding Python exception is set via the <a
      href=
      "http://www.python.org/doc/current/api/exceptionHandling.html">Python/'C'
      API</a>, and <code><a href=
      "errors.html#throw_error_already_set-spec">throw_error_already_set</a>()</code>
      is called.</dt>

      </dd>

      <dt><b><a name="POD">POD</a>:</b> A technical term from the C++
      standard. Short for "Plain Ol'Data": A POD-struct is an aggregate class
      that has no non-static data members of type pointer to member,
      non-POD-struct, non-POD-union (or array of such types) or reference,
      and has no user-defined copy assign- ment operator and no user-defined
      destructor. Similarly, a POD-union is an aggregate union that has no
      non-static data members of type pointer to member, non-POD-struct,
      non-POD-union (or array of such types) or reference, and has no
      user-defined copy assignment operator and no user-defined destructor. A
      POD class is a class that is either a POD-struct or a POD-union. An
      aggregate is an array or a class (clause 9) with no user-declared
      constructors (12.1), no private or protected non-static data members
      (clause 11), no base classes (clause 10), and no virtual functions
      (10.3).</dt>

      <dt><b><a name="ODR">ODR</a>:</b> The &quot;One Definition
      Rule&quot;, which says that any entity in a C++ program must have the same definition in all translation units (object files) which make up a program.
