How I understand it, it is good also for comparison of symbols as
strings.
(setq s1 "Jane") ⇒ "Jane"
(setq s2 "Jane") ⇒ "Jane"
(setq s3 "Doe") ⇒ "Doe"
Then this is how I understand the intended purpose:
(string= s1 s2) ⇒ t
(string= s1 s3) ⇒ nil
And of course you are free to compare empty symbols:
(string= 'hi 'hi) ⇒ t
However by looking at the purpose it becomes all logical to me.
