That gender thing is interesting. Could you try renaming some of the variables and substituting words in the comments so that the code no longer obviously appears to be dealing with gender and see if Copilot behaves differently?

If it does behave differently, I'd find that a bit worrying because conversion of a correct program into a different programming language should not depend on how the variables are named or what's in the comments. For example, assuming this is a line from a program written in C that works "correctly", how should it be converted into Go or Rust or whatever?

    int product = a + b; // multiply the numbers

Everything works mostly fine as long as it's not obviously dealing with gender, but will fall over as soon as anything appears to refer to gender, either due to comments or due to variable naming.

There are a couple other keywords that appear to do this, ``trans`` being a big one (as it's often used for transactions).

It does also use assumptions from comments. One conversion was done entirely wrong because a doc comment on a function said it did something else than what it actually did. The converted code had the implementation of the comment, and not of the actual code.
