For this particular project, Python is a requirement. For the general approach, the answer is more complicated. It depends on what hooks the language implementation exposes -- and even if it exposes enough to make this work in theory, tracking dataflow at the same level of accuracy and granularity as IPyflow does may not be possible without taking an unacceptable performance hit, or without sacrificing portability across language versions. My hope is that the approach can scale to languages like Julia or R, but I'm not as familiar with those languages as I am with Python, and I kind of suspect each language may require its own bespoke tricks. Regardless, for Python it was a journey roughly 3 years in the making (and still ongoing) -- other languages would be easier now that I've learned a fair amount, but the work to add this kind of support is by far the most complex I've ever done.
