```
$ ruby --parser=parse.y -cwe 'x = return a b do end'
Syntax OK
$ ruby --parser=prism -cwe 'x = return a b do end'
ruby: -e:1: syntax error found (SyntaxError)
> 1 | x = return a b do end
    |     ^~~~~~~~~~~~~~~~~ unexpected void value expression
```

I think it's likely because of the wrapped block expression.
