I did:

```
julia> ntup = (1, 2, 3, 4, 5, 6), NTuple{6, Int}
julia> Set(ntup)
Set(Any[(1, 2, 3, 4, 5, 6), NTuple{6,Int64}])
```

But I want to get a set of Int64.

How can I achieve that?

Your first line isn’t doing what you probably think it’s doing. It creates a tuple of length 2 where the first item is a tuple of 6 integers and the second item is the `Type`

`NTuple{6,Int}`

. So of course, the `Set`

constructor which simply takes an iterable constructs a `Set`

with the two items in your outer tuple. `Set((1,2,3,4,5,6))`

works exactly as expected. If you’re getting the length 2 tuple from somewhere else, `Set(first(ntup))`

works as expected.

If you would like to assert that the type of `ntup`

is `NTuple{6,Int}`

, the syntax you’re looking for is `ntup::NTuple{6,Int} = (1,2,3,4,5,)`

.
