Maybe in theory it does not see, but in reality it does see it as
`list' is evaluated before `eval', so the interned `rcd-symbol' and
variable `description' they get evaluated before `eval'.
(defun rcd-db-completing-table-history (table)
"Return symbol of history variable for TABLE.
If TABLE is \"businesses\" the symbol will become
`rcd-db-completing-table-history-businesses' and it will be used
for functions `completing-read' and `read-from-minibuffer'
history.
If a dynamically generated variable does not exist, it will be
generated on the fly."
(let ((rcd-symbol (intern (concat "rcd-db-completing-table-history-" table)))
(description (format "History for table `%s'" table)))
(if (boundp rcd-symbol)
rcd-symbol
(eval (list 'defvar rcd-symbol nil description)))))
