Does anyone know of a general purpose graphical dataflow language, possibly bleeding-edge? Sort of like a PD for everything? Prograph is sort of like this, but there are many aspects of it I do not like, and it is ancient and no longer used as far as I can tell. I personally think PD-like models for programming would be useful in a general purpose context, provided the language had a few additions made to it to support larger programs and more reusable code (which I've recently briefly outlined on the Max list if anyone is over there as well).
So then... anyone know of anything, or is it back to Scheme for me then? I truly believe a "GPGDL" is a viable thing, and I'd love to see it happen one day if it hasn't already. We're getting very close with environments like Max, LabVIEW, etc. I would like to see someone go all the way.
