The expression $this->statement->uses of type PhpParser\Node\Expr\ClosureUse[] is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

            /**

Are you sure the assignment to $variable is correct as $context->getSymbol($variable->var) (which targets PHPSA\Context::getSymbol()) seems to always return null.

                if ($variable) {
                    $this->symbolTable[$variable->getName()] = clone $variable;
