In Phobos (especially in std.algorithm) a lot of specialization between a RandomAccessRange and an InputRange are used even though only an InputRange is required. The reason for this is solely performance - imho we should start to tackle this and remove such specializations. Let's create better code!
Clearly improving range-specific optimizations will "lift all boats". But specializing code for specific range kinds is in principle a good thing. See e.g. the recent thread about nextPermutation - we should not be ashamed to specialize it for random-access ranges.
