Let collections.Reverse work on strings
#12839

If I were looking in our documentation for a template function that reverses a string, I would look for something in the strings namespace. The string "Hello 👋🏿" will be difficult to properly reverse. |
Well, it's not ... impossible. My question is how useful it is. I have not read the discussion linked above; what is the use case and is it a common use case? |
This is the first request I've seen. |

It was a solution (or better: workaround) for a different problem. I would say it's quite unusual and of limited use to the public. But speaking in general, it was quite surprising to me, that there isn't such a function. |

Closing for now. Uncommon use case and non-trivial implementation. |
It is currently hard to reverse a string. This forum thread discuses some workarounds but the best would be to let
collections.Reversedo the job.As @jmooring mentioned in the thread, this could probably lead to invalid unicode strings in case of non-ascii characters (this depends on how strings are represented in go and which set of functions will be used to reverse the string - I am not experienced in go).
So as a limitation it may only result in a reversed binary buffer instead of a usable reversed string.
