<p>Hi Marcel, Hi Chris,</p>
<p><br>
</p>
<p>thanks for your feedback. I see your point of complexity, still, I think BlockClosure #& etc. could be a nice concept, but it would rather belong in an own repository (such as Xtreams, for example). </p>
<p><br>
</p>
<p>See <span>Kernel-ct.1292/2 for the next attempt. :-)</span></p>

Hi Christoph,
<div><br>
</div>
<div>you are proposing an interface to avoid having to deal with Exception >> #pass and #resume:. I like #on:when:do:, maybe renamed to: #on:satisfying:do:. I do not like your & syntax because it would mix Exception, ExceptionSet, and BlockClosure -- which
may be hard to understand and debug.</div>
