This is whatʼs bothering you the most? ;)  I have reread the part of the
elisp manual about reading text from the minibuffer, and it suggests one
“do all minibuffer input as part of reading the arguments for a command,
in the ‘interactive’ specification.” [1]  Not directly applicable to a
stand-alone let snippet but relevant in the context of the thread (which
involved reading user input for an interactive command).
