@Alewandre Sorry, I just realize that I misunderstood the first mail. When you spoke about [inlet~], I thought about the inlets of the objects and not the inlets of the abstractions. My approach is for for externals so perhaps that should be another subject for the round table?

It seems that Enzien audio reinterprets the pd patches and doesn't use the pd code. If this framework acts like gen, it probably generates an pre-optimized C code from a patch (and then the compiler can compile and perform the optimizations). Perhaps I'm wrong but I think that there is a reason why Enzien audio doesn't use the pd code and why gen uses its own objects and not the native dsp objects: they had to rewrite all the code of the objects. I mean, if we want to convert a patch to a perform method (we simplify the approach by limiting the patch to the dsp objects only),  the gen-like object have to know the textual form (or an equivalent) of the perform methods of all the objects. But for the moment, we can only retrieve the addresses of the perform methods and even if we implement a mechanism to retrieve these methods as text, we still have to rethink their syntaxes (because they are surely not usable and not optimized for the new context). Perhaps my explanations are not really clear and perhaps I should keep that for the irl discussion... I just think that such application amounts to recreate a brand new software. It would be great but it would require a lot of work. Considering the existing projects like libpd, FAUST or even Enzien audio, does the prize justify the cost? Sorry if it seems that I want to nip the project in the bud :)

Its an idea I've long supported, for perhaps 10 years.

But there are some subtle dangers to openness.

Given the very small size of Pd patch code in relation
to even the simplest compiled external we might agree a
principle, a standard, an unwritten law if you like....

that any pd abstraction converted by a [gen~] like mechanism
into a compiled external, carries with it the dataflow source
as a data chunk. That means the dataflow source is always distributed
with it. Further the whole process is reversible with a
"convert-external-to-abstraction" process.

What we would have then is a kind of great "folding editor/compiler"
for DSP development where two views of code are possible.
This would be powerful in teaching C as well as data-flow with
the same tool.
