OpenFL ActionScript 3 function overriding

Well @obscure you can target html5 with as3 with OpenFl (through Apache Royale). ActionScript 3.0 Support
Anyway, I don’t know how this works, never tried, there may be little quirks, maybe the Apache Royale community can answer. I don’t know where OpenFl is involved, maybe it adds Tilemap and few other features.
