<p>
A type alias is a statement of the form:
</p>
<div class="code"><pre>
using PFD = void (*)(double); // New introduced syntax
</pre></div>
<p>
which is equivalent to the old style typedef:
</p>
<div class="code"><pre>
typedef void (*PFD)(double); // The old style
</pre></div>
<p>
SWIG supports this kind of statements.

The following is an example of an alias template:

Similarly for non-template type aliasing:
</p>
<div class="code"><pre>
using PFD = void (*)(double); // New introduced syntax

A warning will be issued:
