Convert set to container X++

Recently I've faced with a task - I had two sets and I need to check item by item for both of them to identify number of common values. Going with Enumerator or Iterator would be the obvious way. However, I wanted to eliminate of ambiguous code and found different way. I converted SET to Container and checked elements one by one. Maybe it's not the best solution from performance standpoint (yes, I'm aware of slowness of containers), but it's the simplest one. So, the actual conversion of the Set to Container I did via next code:

Set incomeSet = new Set(Types::String);
cntainer outputCon;
//filling in set.
outputCon = condel(incomeSet.pack(), 1,3);

The

condel()

funciton deletes all special symbols and other staff and in the end you'll get something like that:
