Original issue submitted by @adrianton3 in babel/babel#5529

Input Code

a ? () => ({}) : b => c

repl link

Babel Configuration (.babelrc, package.json, cli command)

See the link to the repl

Expected Behavior

The code should compile to

a ? function () {
  return {};
} : function (b) {
  return c;
};

as it does if the react preset is not mentioned

Current Behavior

repl: Unexpected token, expected : (1:23)
> 1 | a ? () => ({}) : b => c
    |                        ^

Your Environment

Getting this in the online repl; the latest release as of 23 mar 2017 is 6.24.0 assuming the repl is using that.
