Hegel: delete doesn't count as turning a property to undefined

[Mathspy]

function plus1(x) {
    return x + 1;
}
let y: { z: number } = {
    z: 5
};
delete y.z; // if you switch this line to y.z = undefined it will produce an error
let result = plus1(y.z);

This should return an error because type undefined is not compatible with type number

Also lovely work so far!

Oh, yes. Currently, we don't support delete. But it's should be supported. So, we will try to add support of the case. Thank you a lot for your contribution ^_^

Oh I see! Is there a list of currently unsupported features I can look at before reporting them since they are already known?

[JSMonk]

Unfortunately, there is no kind of list. So, if you will report it in issues, it will be great.

Fixed in 0.0.43 release. Thank you for the contribution ^_^.
