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.
