Log:<br>
add ::drop_back() and ::drop_front() methods, which are like pop_front/pop_back on a vector, but a) aren't destructive to "this", and b) can take a # elements to drop.<br></blockquote><div><br></div><div>FWIW, the string_ref proposal for standardization provides pop_front and pop_back with an N that is the number of elements to pop... Would it be worth following that lead, and just copying the string ref before calling them? I'm particularly interested in the use case for returning the adjusted string in case we should add these methods to the standards proposal.</div>
</div></blockquote><br></div><div>I'd be fine with adding that as well if people would find it useful.</div><div><br></div><div>-Chris</div><br></body></html>
