Supporting syntax allowed by JScript

[chinmaydd]

Hey @HynekPetrak, great project! 👍

This is more of a doubt, rather than an issue and would like to hear your thoughts on the same. I have seen syntax which is non-compliant to the ECMAScript standard supported by JScript. For example:

function a () {
} 

function a.prototype.b () {
}

c = new a();

c.b();

How do you think is a proper way to handle such files in the jail?
