Oberon SET concept

[The-Futurist]

Is there anything in C# (already exists or under consideration) that corresponds to the SET as defined in the Oberon (and earlier Wirth) languages?

The BCL offers BitArray and BitVector32 data types. C# has no special data types for this, it only offers integral data types and bitwise operators on them.

That is very similar, implemented in a compact manner, thanks. Do you now where it gets used? what kind of problems leverage it?

I used one in our implementation of our bloom filter, to store booleans at particular offsets for hash hits. Compiler uses something very similar to work with control-flow blocks (like if they are reachable or not), definite-assignment tracking, nullability-analysis, etc. . They are good for problems where you have a lot of indices for things you want to store bools with, and you'd like the space for that to be compact.

Thanks.
