@flowtype any documentation on this? :) I'm a bit confused :)https://twitter.com/Jack_Franklin/status/903601663306600449 …
they don't mean anything, it's like how you can name a variable $ in JS. they're typically used to "namespace" variables though

makes sense; I thought that might be the case given no specific docs but wanted to check. I'm loving Flow so far :)

Initially they were only meant for "internal" features, but we're long since past that. I want to use proper namespaces for these types.

e.g.
$Keys -> Object.Keys
