Arithmetic\Evaluate()

Evaluate mathematic operations

<?php$compiler = \Hoa\Compiler\Llk::load(
new \Hoa\File\Read('hoa://Library/Math/Arithmetic/Grammar.pp')
);
$visitor = new \Hoa\Math\Visitor\Arithmetic();
$result = $visitor->visit($compiler->parse('10+10'));

I wrote tests on an other branch, theses passes :)
