`tm_setunion`

Function

The `tm_setunion`

function takes multiple sets and produces a single set containing the elements from all of the given sets. In other words, it computes the union of the sets.

hcl

`tm_setunion(sets...)`

## Examples

```
tm_setunion(["a", "b"], ["b", "c"], ["d"])
[
"d",
"b",
"c",
"a",
]
```

The given arguments are converted to sets, so the result is also a set and the ordering of the given elements is not preserved.
