Hi Stjepan,

A couple of months ago I saw a talk by Bdale Garbee about the GNU Radio
project ( They're doing various kinds of
impressive-looking radio-related DSP on PCs. IIRC they currently have
something where they write Python code to glue together C++ building
blocks using some sort of data flow notation, but their next version
will not require the Python layer. It may well have some useful
material for you, or they may be interested in your code.

Personally, I'm interested in something that is superficially similar
to this but with some make-like dependency tracking included. I
imagine changes to one data structure "flowing" through to other
structures that depend on it. This needs to be between threads, and so
not changing the dependent data while it is in use is one of the
challenges. (I only have the vaguest idea what I really mean by that.)

With computers getting more and more parallel all the time, we should
all be looking for ways to make our code more concurrent! Providing a
reasonably "natural" way to "plumb together" functions could be one way
to do that.
