The docs for Tree::Simple say, a couple of times, that it is pure Perl.
However, it is not.

Here is an extract from the docs for my new module:

<==8><==>
=item Why did you use Tree::DAG_Node?

One constraint (design goal) was a pure Perl HTML parser.

Tree, for example, uses Scalar::Util, which uses List::Util, which uses
XS.

Tree::Simple has the same drawback.
