@barto You are right. I thought that was synonymized to back then, too.
However, I do not have big enough score in to suggest synonyms or vote for them.
I am not sure whether the synonym should be $\to$ or $\to$ .
But even if we do not want to do neither of these two, at least adding $\to$ seems like a useful thing to do.
