Re: print-circle and describe-variable

[Richard Matthew Stallman]

    My point is whether this is even necessary for realistic Emacs usage.
    In practice, are there any significant Emacs variables containing
    circular structures, that users will want to look up using
    describe-variable?

We are now talking about setting print-level and print-length.
Those are useful for looking at any sort of large value.
Not only for circular values.
