my-fn takes a number and a string as argument and outputs a string.  I am 
using map-indexed and my-fn to comprehend a list of items with numbered 
index as follows, 
 
 
(map-indexed (fn [idx itm]  (my-fn idx itm)) '(list-of-crap))
 
When i run this on the repl everything works well and I get a single long 
string of output. But, I am trying to use the output of this function in a 
report and it is not working in that context.
 
The code to generate report looks something like this:
 
 (str
      string1
      string2
      string3
    (map-indexed (fn [idx itm] (my-fn idx itm)) '(listofcrap))
      string4....etc...
)
 
The code above will just print out 'clojure-lazy-seq' instead of the string 
output.  If I try:
 
(apply str  (map-indexed (fn [idx itm] (my-fn idx itm)) '(listofcrap)))
 
Then I get the last item from my list properly formated in the report, but 
that's all.  How do I print out everything?  Thanks
