>>>I wanted to say that even if a priority of some STL-based processing ( a function, or a set of functions, etc ) is boosted to Above Normal or Time Critical it can not outperform a processing ( a function, or a set of functions, etc ) implemented in pure C language>>>
This is quite interesting observation.
More than one month ago I posted question about the problem related to using #pragma prefetch on STL std::vector. I observed during the compilation phase ICC issued warning about the incompatibility of that #pragma and simply disabled it. Now by reading your answer I came to conclusion that probably ICC did not recognize std::vector as a plain dynamically allocated array (template parametrized on T) wrapped in object.

@Sergey
What is your opinion on template meta-programming as a mean of compiler type safe attempt to perform some computation at compile time? Judging by my own experience inclusion of small meta-functions can actually be "computed" at the compile time. Here I mean "metafunctions" for computation of trigo functions (without extensive argument checking).
