Flow - doesnt support special char string type keys in object

[bradennapier]

type SystemStatsEvent = {
  '@timestamp': number,
  '@projectIdentityID'?: string,
  '@systemIdentityID'?: string,
  '@userIdentityID'?: string,
  '@dealerIdentityID'?: string,
  hostname?: string,
  alarm?: boolean,
  cpu?: number,
  mem?: number
};

This is not allowed i get an error:

TypeError: Cannot read property 'charAt' of undefined

As far as I can tell the way I specified these keys with the special characters is the appropriate way to do this. Flow does parse it correctly.

Yep, that's a bug. Thanks for the bug report! Looks like we're expecting raw properties in our properties inference and need to potentially use babel-generate instead.

[bradennapier]

Ok, makes sense! It's a fairly out-there syntax that took me awhile to figure out / I don't even know if it is documented anywhere!

Here is what it is producing, surprisingly it doesn't actually produce an error!

Fixed in #911 - going to roll a new release & close as soon as I finish a new bunch of tests.

Fixed in 5.3.2 thanks to @mrtnbroder !
