It's in RangeEx, which was just added to the Range library in 1.43. The only difference between it an std::copy is that boost::copy uses an input range rather than two input iterators.
Ah, thanks. I'm familiar in general with how Range updates the standard algorithms to use ranges rather than loose pairs. The loose pairs of iterators is something that turned me off about the STL proposal in its earliest days. --John TradeStation Group, Inc. is a publicly-traded holding company (NASDAQ GS: TRAD) of three operating subsidiaries, TradeStation Securities, Inc.
