FWIW, I'm not suggesting any changes, but I admit that I never really
understood this design decision.

This is what I get in Guile:

    scheme@(guile-user)> (string=? "foo" 'foo)
    ice-9/boot-9.scm:1676:22: In procedure raise-exception:
    In procedure string=: Wrong type argument in position 2 (expecting
string): foo

And in SBCL:

    * (string= "foo" 'foo)
    NIL

    * (string= "foo" 123)

    debugger invoked on a SIMPLE-TYPE-ERROR in thread
    #<THREAD tid=259 "main thread" RUNNING {7004FF0003}>:
      123 is not a string designator.
