It seems that ~:{...~} will behave the same as ~{~1{...~:}~}. Likewise
··@{...~} and ·@{~1{...~:}~} should be equivalent unless I'm missing
something. So am I missing something?

In LW:

CL-USER 6 > (format t "~:{~A ~}" '((foo) (bar) (baz) (quux)))
FOO BAR BAZ QUUX
NIL

CL-USER 7 > (format t "~{~1{~A ~:}~}" '((foo) (bar) (baz) (quux)))
FOO BAR BAZ QUUX
NIL

CL-USER 8 > (format t ···@{~A ~}" '((foo) (bar) (baz) (quux)))
(FOO)
NIL

CL-USER 9 > (format t " ·@{~1{~A ~:}~} " '((foo) (bar) (baz) (quux)))
 (FOO)
NIL

The first and second do yield the same result. But the third and fourth are 
slightly different. Note the result (FOO) is indented by one space in the 
last example.

Uh, don't you think that has something to do with the extra space at
the beginning of the format string. ;-)
