Hi folks<div><br></div><div>In Fuel, we serialize a block closure with its state, including its outerContext. This enables to serialize a sorted collection with its sortBlock:</div><div><br></div><div><div>| bytes result |</div>

<div>bytes := FLSerializer serializeToByteArray: (SortedCollection sortBlock: [:a :b | a &gt; b ]).</div><div>result := FLMaterializer materializeFromByteArray: bytes.�</div><div>result�</div><div><span class="Apple-tab-span" style="white-space:pre">	</span>addAll: #(1 2 3);</div>

<div><span class="Apple-tab-span" style="white-space:pre">	</span>yourself.</div><div>---&gt; a SortedCollection(3 2 1)</div></div><div><br></div><div>Here the problem: the�byte array is huge! (800kb) because we are serializing unneeded context for the sort block.�</div>

<div><br></div><div>We wonder how to prune it and save time and space.</div><div><br></div><div>Thanks in advance</div><div>Mart�n</div>
