Object rest spread doesn't work in non-declarations
tolmasky opened this issue · comments
As far as I know, "{ ...rest } = x" should work fine. It seems to work in node 8. However, Babylon only allows it in declarations (let/var, etc).

You need parentheses, same as you would for object destructuring without a rest, or for an object literal as a statement by itself.
Ah, indeed, I guess node REPL auto-wraps and that is why > { ...rest } = {} works.
