True. However, the first CPP returned is always the one which must be

In the current system you can describe it by creating a generator STATIC_DATA
<- ECPP, which will
1. Create CPP from ECPP by recursive call to 'generators.construct'.
2. Take a first CPP and convert it to NM_ASM by another call to
3. Convert NM_ASM to STATIC_DATA
4. Return STATIC_DATA and the second CPP
If you take a look at Jamfile for part of this example, still at
you'll notice similiar approach.
It's not automatic, but user can be asked to do such things for complex
transformations. And it must be able to do that.
