Maps can't use some keys types (Int64, Float, Bool...) since the new Haxe 4.3.0 version
Trying to create maps with some types as key gives an error : Abstract haxe.ds.Map has no @:to function that accepts haxe.IMap<haxe.Int64, Int>
I realized it with the Int64 type but then, I've been talking about this on the Heaps Discord and Yanrishatum (<3) found out it also applied to Float or Bool. Their theory is that it's linked to @:runtimeValue.
Here are some examples : https://try.haxe.org/#18552329.
I think that's more an Haxe issue than an Hashlink one. We did change Int64 to be a native type but we haven't yet introduced a 64 bit Map in Haxe for all platforms.
I'm not sure if and how these used to work, but that was more by accident than by design :)
Oh, I see. As it worked in JS, I thought it was a HL issue. My bad. Should I open an issue on the Haxe git ? It used to work in a broken way. The Int64 was an Object so it was comparing reference and not value.
