Hi, Christoph.<div><br></div><div>The method finder (or selector browser) has a hard-coded list of possible results (or messages) to not trigger dangerous side effects. Any new feature, such as that "quasi higher-order-message" symbol , would have to be added. Sure.

<p>Hi all,</p>
<p><br>
</p>
<p>I just got irritated as I evaluated</p>
<p><br>
</p>
<p><span>MethodFinder methodFor: {{#(1 2). #even}. #(1)}</span></p>
<p><br>
</p>
<p>and got no hit.</p>
<p>This is because the MethodFinder stores an extra list of selector parameters that are assumed to require a block argument (Blocks) -- but nowadays this requirement is not given, as you can pass a Symbol, MessageSend, SortFunction or whatsoever, thanks to
polymorphy. So (how) is this block check still relevant? If I remove it, I get the right hit and can do thinks like</p>
<p><br>
</p>
<p><span>MethodFinder methodFor: {{#(1 2). #yourself descending}. #(2 1)}.</span><br>
</p>
<p><span><br>
</span></p>
<p><span>Also, #ifError: will prevent any error thrown if the block does not match the selector.</span></p>
<p><br>
</p>
<p>Looking forward to your answers :)</p>
