The point is not that it's a lot of work. It's that the idea to 
re-implement FFT from scratch inside Boost is foolish, given the 
availability and quality of existing FFT libraries.

That being said, if you think you can come up with a better API (using 
modern C++), I think there *might* be value in providing (very thin) 
wrappers around those existing libs. But reimplementing them from 
scratch, and hope to get to a similar level of quality with a reasonable 
amount of effort, that's extremely naive.
