Hi,

I have a use case where I'd like to load small forms in String format from 
a database and wrap them in functions. This is to support some basic 
runtime customisation.

I'm having problems getting read-string and macros to play nicely, a 
problem which can be distilled as below:

; a simple macro to return a fn
(defmacro xr [f]
  `(fn [] ~f))

; calling the macro normally
(apply (xr (println "hello")) []) ; nil (and prints hello)

; calling with the result of read string
(apply (xr (read-string "(println \"hello\")")) []) ; (println "hello") 
(and prints nothing)

I'm sure I'm missing something very obvious here but I had assumed that 
since (= '(println "rob") (read-string "(println \"rob\")")) that the above 
example would work.

Regards,

Rob Harrop
