Is Polyglot Programming Really a Thing?

on YouTube ↗30m

" summary

Polyglot code is common: examples include OpenJDK and TensorFlow mixing C, C++, Java and Python, and frameworks using CUDA/OpenCL kernels embedded as strings that escape static analysis. Native bridges like JNI and Erlang NIF force brittle, handwritten type and memory mappings. Experiments on large repos show OpenJDK’s 30–35k tests and a regression-selection prototype that currently misses about 10% of relevant tests. Real failures include silent int→float promotions in GPU kernels that produce wrong results.
