Review for NeurIPS paper: Unsupervised Translation of Programming Languages

Additional Feedback: - Would have been great to see more discussion on what are the challenges of translation for programming languages vs. natural languages. What challenges are unique to source code? Just off the top of my head: APIs and libraries variable names compositionality purity / side effects scoping rules types - The problem of programming language translation is rarely the syntax of the language itself, but rather the semantic differences between the languages, and even worse, between their underlying libraries. I had hoped for a more elaborate discussion of this point. Looks like name and signature of the method would be critical for the translation to be successful?
