I’m glad it works! Though I just realized that the function I gave you gives you `Symbol`s, not the types themselves. If you want the types themselves, define `make_nt` as:

```julia
@inline make_nt(T) = NamedTuple{(symbolize(T),)}((T,))

```

And then in `get_unique_types`:

```julia
return values(ntc)

```
