<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>
<dd><br>

<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><br>

<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>

Rule", 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.
