</div>how about providing such check only in *debugging* version of library?<br>
<div class="im"></div></blockquote><div><br>I think the decision whether to include specific check should be left up to the developer. Perhaps I would like to retain only a subset of checks, while debugging version restricts my freedom and I would end up writing my own version. Giving functions with and without checks is a good way of giving such freedom.<br>
