Another format

[vlad]

(format t "")
=> nil

(format nil "")
=> ""

(format t "<#aaa>")
=> <#aaa>

[David Vázquez Púa]

the third one is not true. It prints <#aaa> but it returns NIL, as the first one:

so I think this is the desired result.

Yes, I did not correctly use the local message editor.
Sorry.
It must be so:

(format t "<aaa>")
=> nil
(format nil "<aaa>")
=> "<aaa>"
(format t "<#aaa>")
=> <#aaa>

It is rather a feature I/O,

not an error.

[David Vázquez Púa]

No problem. Can I close it this issue then?

[vlad]

Yes, of course.
