For those not already familiar with Haxe perhaps the most interesting property is the huge variety of transpilation targets (1). I would not call the resulting code highly readable, but I don't know of anything else with this level of targetability.
C++, Lua, and JavaScript all have had improvements in their readability over the years. I don’t write much Haxe at all, but have followed it for a while. It’s such an ambitious project, even featuring over the years at least 2 different VMs.
