Subject: Backquote idioms
And consider the useful but not CL-supported ,,@ .
Much to my surprise, I find that
(a) ,,@ *is* supported by Common Lisp.
(b) ,,@ is equivalent to ,@(list ,@
I obtained these results by working through the expansions of
`(foo `(bar ,,@x))
and `(foo `(bar ,@(list ,@x)))
using the rules on pages 349-350 of the CLM.
