TypeScript: Convert a bool to string value

I am unable to convert a boolean to a string value in TypeScript.

I have tried to use the toString() method but it does not seem to be implemented on bool.

Updated for comments!

You can now use toString() to get a string value from a boolean type.

var myBool: boolean = true;
var myString: string = myBool.toString();
console.log(myString);

This outputs:

"true"

And has no errors or warnings.
