From the docs (and experiments) I assume that the HISTORY parameter should be a symbol and not e.g. a literal list. However, I don't really need to /save/ the input I get into the history, since each time I use read-string, the history is regenerated anyway from external source (I'm working on a client for certain web service, and the history is kept on the server, so it really doesn't make sense to keep all those in my Emacs session.) Is it fine to use a temporary, let-bound variable name as the HISTORY parameter, or is there a better way for a "history" I only need to read from, not to write to?
