The main reason why it caused issues is this nice idiom:

if(auto arr = someFunction())
{
    // use arr
}

This would HAVE to be split out to two statements, and the arr variable
would be scoped outside of the if statement.

I wish the language would accept:

        if ((auto arr = someFunction()) !is null)
        {
                ...
        }

But IIRC, auto cannot be used except at the top level expression.

You want !=, not !is.
