Hi Vladimir,

I tested some code in my Jamfile :

========================================================
import errors
;

result = [ modules.call-locally errors.lol->list 1 : 2 : 3 : 4 : 5 : 6 : 7 :
8 : 9 ]
;

ECHO $(result)
;

EXIT ;
========================================================

I got result  "1" : "2" : "3" : "4" : "5" : "6" : "7" : "8" .
:)
