Unit Propagation - Asking ChatGPT for a Slanted Math Operator

For my thesis, I needed a code listing with a circled plus (⊕) in a comment. This is more or less possible with my current setup: using the mathescape option of listings, I can drop into latex mode in the middle of a listing using (*@ latex code @*). There I can then use plain math mode to make a circled plus appear:

\begin{lstlisting}[style=java]
// Let's compute: a (*@\color{listingcomments}$\oplus$@*) b
\end{lstlisting}

You might not notice it on first look, but in my opinion, there’s a problem here: the plus is not slanted! I want this for consistency with the comment style. After some back and forth with ChatGPT, encouraging/coercing it by mentioning that I really don’t mind a hacky solution, it generated the following definition for \slantedoplus (formatting mine):

\newcommand{\slantedoplus}{%
  \tikz[baseline=(op.base)]%
    \node[inner sep=0pt, outer sep=0pt, scale=1, xslant=0.2]%
    (op) {$\oplus$};%
}

\begin{lstlisting}[style=java]
// Let's compute: a (*@\color{listingcomments}$\slantedoplus$@*) b
\end{lstlisting}

The definition can still be improved. E.g. I still need to guess the number to put into the xslant argument to make it fit with the style used in this document. Since I don’t expect I’ll change the listings style, I don’t mind hardcoding a guess. Also, the scale=1 argument doesn’t do anything as far as I can tell; removing it does not seem to change the slanted plus symbol. Finally, probably this operator is not spaced properly at all in math mode, because it’s essentially just dumping a tikz picture inline.

This is all acceptable for me: it looks exactly like what I had in mind, and I only need it for some simple formulas.

As I said, it took a few tries to get here. The first iteration of \slantedplus ChatGPT suggested was just a rotated \oplus; it looked horrible. The second iteration it got creative with a bunch of latex commands, but when I compiled it in my own latex editor the command ChatGPT suggested just produced a regular \oplus that did not slant. After mentioning this, ChatGPT generated the definition you see above. You can inspect the conversation here.

I’m posting this here because I’m not sure posting this on Stack Overflow will be appreciated by the moderators there. Instead, by posting it here I’m hoping the search engines will eventually pick it up and that people who need to slant their operators will find this. In so far it is actually legal for me to do so, the license for the above code snippet is MIT.
