Copy two Memb<UInt> without duplicates
Hi, I have lots of tiny Memb<UInt> containers. Each contain about 5-8 elements. There are already several duplicate UInts in the containers. I want a function:

void copy(Memb<UInt> &a, C Memb<UInt> &b) {
// copy contents from b into a, but don't allow for duplicate UInts
}

This will likely be called 5 to 30 times for each container.

Any ideas on an elegant way to do this? Should I consider sorting? Or is my only option checking each element in two nested loops.

Thanks for your thoughts,
Chris

simple solution: REPA(b)a.include(b[i]);

Neat trick! I missed that one in the header smile
Will try this, if performance is an issue will see if it can be optimized with sorting.

Thanks
