providor_symbol_map is an Associative Array, so you can't sort 
that. *Usually*, you want to do what the OP did, which is to get 
the keys, and sort them, but leave the AA unchanged. EG:

Val[Key] myAA;
Key[] mySortedKeys = myAA.keys.sort!((x, y)=> compare(myAA[x], 
myAA[y]))()

//Print values in incremented order:
foreach(key; mySortedKeys)
     writefln("%s: %s", key, myAA[key]);
