I'm not sure if I'm overlooking something or if this is a stupid question, but... Why not use JavaScript getters?

JavaScript objects have support for getters: (works everywhere except on IE8)

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Working_with_Objects

Why not use them (optionally) instead of .get() and .getIn()? Especially for server-side code and for applications that aren't focusing IE8 this could be really helpful.
