<p>Hi all!</p>
<p><br>
</p>
<p>Just another, possibly crazy idea: What about implementing #cull:, #cull:cull: etc. on Object?</p>
<p><br>
</p>
<p><b>Object >> #cull: firstArg</b></p>
<p><b> ^ self value</b></p>
<p><br>
</p>
<p>This could improve the polymorphy between "evaluables" such as blocks or MessageSends and other objects. Example:</p>
<p><br>
</p>
<p><span>[2 / 0] on: ZeroDivide do: Float infinity</span><br>
</p>
<p><span><br>
</span></p>
<p><span>Some current implementations that call both #isBlock and #cull: also reveal that there might be a small break in the interface. From #haltIf:</span></p>

</span></p>
<p><span><br>
</span></p>
<p><span>Just wanted to share that thought :) In general, do you think blurring the differences between block and object in that way might be a good idea or rather a bad one? At least we already have implemented #value on Object.</span></p>
<p><span><br>
</span></p>
<p><span>Disclaimer: I know that in many cases, you should prefer a block for performance reasons/compiler optimization, but there is still a gap between the interfaces ...</span></p>
<p><span><br>
</span></p>
<p><span>Best,</span></p>
