strictNullChecks and undefined values in class

[nicolashenry]

TypeScript Version:

1.9.0-dev.20160613-1.0

Code

class Greeter {
    greeting: string;
    constructor(message: string) {
        // do nothing
    }
    greet() {
        return 'Hello, ' + this.greeting;
    }
}

export let greeting: string = new Greeter('world').greeting;

// greeting is undefined
console.log(greeting);

Expected behavior:

I would expect the compiler to complain about greeting not being assigned at least once in constructor with strictNullChecks flag activated.

Actual behavior:

The code run without error.
