I can special polynomials such as Chebyshev or Legendre and special
functions such as Bessel coming up.  But these aren't really
algorithms/filters in the signal processing sense - they are building blocks
on which such algorithms are built. More than being a "problem" of overlap,
I can imagine Boost.Math being a very hand leg-up to the author of this
proposed library.

There is an explicit example in your link actually - it offers a Chebyshev
filter. This is not offered by the Boost.Math library. However it can be
implemented in terms of the Chebyshev polynomials which *are* offered by
Boost.Math.
