nice idea in theory however c++ and the associated template library
it uses will not make it into the linux kernel.

i took a look yesterday at _pyrtl.py, i did not realise it actually creates
*python* code which is eval'd and compiled and then executed as a nameless
function.

this is extremely cool because the python code (which can be inspected
by enabling a debug os.ENV var) is very basic and conversion to c should
be extremely easy.
