I've tried several ways, can't find how to check.

#define is_empty_list(l) (!l || !l.len) //This also checks to see if the list exists; I don't know if you want that or not.

//You'd just use this like so:
var/list/lst = new
if(is_empty_list(lst)) world << "This list is empty."
else world << "This list is not empty."

Look up the list variable 'len' in the DM Reference (here or via F1 in Dream Maker).
