Vote for this answer if you agree that looping should be renamed to loops which fits with, for example, Stack Overflow, and just seems more professional.
- From a teaching perspective the concept of looping is sufficiently complex to warrant it's own tag, loops to remain consistent with other related sites seems worth the effort. Splitting the tag into its variations, however, seems a little excessive. For pedagogical use, all the loops are sufficiently similar as to admit one tag.
- Ignoring the idea of if it should be renamed or not, I think that the loop type tags will all arrive in their own time if they're needed. Currently, they're not needed and so don't exist.
