I suppose the ideal way to do it would be benchmarks for the (1) idiomatic and (2) the highly tuned implementations. Then the compiler writers can push 1 towards 2, while the pesky shootout implementers can move the goalposts of 2. ;-)
In reality this may just foster a small set of horribly specialised optimisers in the compilers, with little benefit for real-world usage. :-(
i disagree. when i write some general-purpose library, i use these optimization tricks to make library as fast as possible. and wide audience of library users will benefit from such low-level optimizations great example of such low-level optimized library is ByteString which provides C-close speed with very high-level interface -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
