You need something to construct a graph. Why not pick a well-known language already used in scientific computing and stats/data science? The other options are: pick a lesser known language (lua, julia) or a language not traditionally used for scientific computing (php, ruby), or a compiled language most researchers don't know (C++), or a raw config file format (which you would then use code to generate). What's really crazy is using Pure, Idiomatic Python which is then Traced to generate a graph (what Jax does). I want my model definitions to be declarative, not implict in the code.
