It's not like auto result = array(map!"to!string(a)"(uniq([1, 2, 2, 3]))); is a pain either. It's just ordered differently. But regardless, it's easy to get an eager result by calling array on a lazy range, so there's no point in adding eager versions. They'd just be duplicating code for no real benefit. Not to mention, if anyone having to call array on ranges all of the time, you should probably rethink how they're using ranges. It's definitely necessary some of the time, but most of the time, you can just operate on the lazy ranges and save yourself unnecessary allocations. - Jonathan M Davis
