--- Comment #2 from John Leidegren <john at leidegren.se> ---
I would like to add to this that BigInts don't appear to work as keys in ES Collections. I just took Safari 14 for a spin and ran into the most bizzare bugs where I could insert multiple entries with the same bigint keys in a Map.

For example:

const m = new Map()
m.set(1n, 123)
m.set(1n, 456)

console.log(m)
Map {1n => 123, 1n => 456}

get(1n)
undefined

etc.

Not sure what's up but it is broken.
