It is true that a function value can not be printed and then read back in,
but I don't think that's releva
Function values can't be read by the reader. I'm not sure how any versions
of this code work.

Your macro:

Is producing a list of a function or closure followed by a symbol. The
first element of the list your macro builds must instead be an expression
that can be evaluated to a function. (For example a symbol naming a
function or an (fn [] ...) expre

I think you are right, when ever the function returns a closure I get the
exception. I think it should work with closures anyhow.

I don't know why it doesn't work. However, changing defgreeter to the
following seems work.
(defmacro defgreeter [greeter-name]
(let [greeter (make-greeter)]
`(def ~greeter-name ~greeter)))
Might be a clue. :)

I think it has to do with the closure in the *fn *used when generating the
form in the macro.
If you change this function:
*(defn make-greeter []*
* (let [message "hello"]*
*(fn [user-name]*
* (str message ", " user-name*
To this one:
*(defn make-greeter []
*
* (fn [user-name]*
Hi,
I have this macro (complete file https://www.refheap.com/paste/7633):
*(*defmacro defgreeter [greeter-name]
*(*let [greeter *(*make-greeter*)*]
`*(*do
*(*defn ~greeter-name [user-name#]
*(*~greeter user-name#*)**)**)**)**)*
It works as expected when make-greeter is
