During FOEACH's review, extensive performance tests showed FOREACH was 
only about 5% slower than the hand-coded equivalent on average. I 
suspect there may be something wrong with your test. Have you compiled 
with full optimizations? Defined NDEBUG? The code you've posted is 
obviously not what you are running your benchmarks with -- it takes no 
timing measurements. Perhaps you can post your code.
