I looked at Intel's array building blocks and tried to understand how
they were doing JIT. More here :
http://nonchalantlytyped.net/blog/2010/09/26/deconstructing-intels-array-building-blocks/
Basically, they use a mix of operator overloading and some cleverly
named macros to make C++ statements "generate" abstract syntax trees
at run time, then JIT it to SSE supported by thread building blocks.
