I don't disagree with this. But we've got a function that we're asking<br>
to return one of 2 things, as you say. How is this normally handled? I<br>

(loader, list_of_portions). That seems way more straightforward.<br></blockquote><div><br>+1. It's also easy to implement.<br><br>I'm not sure why we *need* a list of portions, but if we do, simple return values seem like the way to go. But the 2-element tuple wins even in the single path portion case, and the tuple-return protoocol is extensible if we need more data returned in future anyway.<br>
