Ah, now I&#39;m understanding your point better. You&#39;re postulating a version
<div>of for_each which requires copy and assign, just for the purpose of exposition.</div><div><br></div><div>Got it, thx!</div><div><br></div><div>Boost.Range sliced does its slicing by calculating iterator offsets from the</div>


<div>begin and end of its source range, which is why it needs random access iterators.</div><div>Its iterator type is also hardwired to be the iterator type of its source range.</div><div><br></div><div>Frankly I do wonder at wisdom of some its design decisions.</div>


<div><br></div><div>How is this done by OvenToBoost&#39;s dropped and taken adaptors? Can you</div><div>point me to the source code?</div><div><br></div><div>Thx, Rob.</div></blockquote><div><br></div><div>OvenToBoost&#39;s repository is here:</div>

<div>`taken` and `dropped` don&#39;t use random access, and use forward access.</div><div><br></div><div>Thanks,</div><div>Akira</div><div><br></div>
