Sorting array with different order

Such questions are better asked in D.learn newsgroup.

Every time you instantiate the sort function with different 
template arguments, you generate a different type. So you could 
use a variant, or probably better to find a different solution. 
You could store just the arguments of the sort template, like the 
string "a.ipAddress < b.ipAddress" or the equivalent lambda, and 
later use it as arguments to instantiate the sort when you need 
it.
