Why is "export default var a = 1;" invalid syntax?

I should first say: no module syntax changes for ES6. But we can discuss
extensions for post-ES6 proposals.
I was resistant to this syntax at first but I've warmed to it. In
particular, it has a consistent syntax, and can be given a consistent
semantics, to `export default function` and `export default class`. IOW, it
creates a local binding that is also exported, but renamed to `default`.
This does feel like a missing case on top of those other "locally named
default export" forms.
Note that if we add `export default var` we also have to add `export
default let` and `export default const`.
I think this is worth proposing, folded in with other proposed post-ES6
extensions to the module syntax (in particular the module metadata syntax).
I'll be happy to do this.
Thanks for your input!
