I often write the code in D (sometimes I start from Python and 
then I convert it to D), get it right, write down more tests, 
then I slowly lower the level of the D code keeping it correct 
with help of the tests, and then convert it to C.

When the code is quite complex, if I do this I waste some time, 
but it's a known amount of time, while if I follow a more direct 
route, writing the C code directly, I can't tell how much 
debugging time I will need.
