I'm not sure how to make this any better. You basically got exactly what
you asked for, given how it's documented to work:
In interactive calls, the replacement text may contain `\,' followed
by a Lisp expression used as part of the replacement text. [...]
`\#' itself [stands] for `replace-count', the number of replacements
occurred so far
So you wrote:
(replace-count)
which is indeed not a function.
The error message could perhaps be wrapped in "Error evaluating
replacement expression: <actual error message>"; but I'm not sure that
would have helped you decide whether it was an internal issue or a
mistake on your part. Special-casing your particular error does not seem
worth it to me.
