WITH-TEMPORARY-FILE gives warnings when pathname variable is not used
I had some code with with-temporary-file
that did not use its pathname
variable in the block after :close-stream
. Specifically, I had code in the block before that took the namestring
of the pathname and used that in the suffix.
This caused an "unused variable" warning to be raised.
This can be fixed by declaring the pathname variable to be ignorable
in the suffix (the "after function").
