Because the shorthand only requires an Identifer, and an IdentiferName is not
sufficient. If the rule allows arbitrary IdentiferName, then we will also allow
`{if}`, which makes no sense it all. So if we really want to allow this, it
would be a special rule in addition to the current rule. In this sense, we are
not forbidden the use of `{this}`, but instead we don't have the rule to allow
that.

Subject: {this} object literal
Hi.
Is there any specific reason why {this} literal is forbidden? Babel had a bug
allowing this and it was pretty convenient to enter console.log({this,
arguments, externalVar}) for quick printing scope.
