This is precisely what I would expect to happen.
There is a postfix `i` operator for things like `1i`, but there is
also a constant `i`
# from src/core/Complex.pm6
constant i = Complex.new(0e0, 1e0);
When you do `-i` you are negating both the `0e0` and the `1e0`.

(-0 -1)
Note that you can't just do `-1i` either, because postfix operators
`i` happen before prefix operators `-`.
So you need to do `(-1)i` or `0-1i`.
