calling match on an abstract leads to runtime error

[frabbit]

import haxe.ds.Option;

abstract A<T>(T) from T to T {
  public function new (x:T) this = x;
}

class Test {
    static function main() {
        var a = new A(Some(1));
        trace(a.match(Some(1)));
    }
}

Output:

Called from ? line 1
Called from Test.hx line 12
Uncaught exception - Invalid field access : match

It picks up this function as a static extension: https://github.com/HaxeFoundation/haxe/blob/development/std/haxe/EnumTools.hx#L201

That's very silly... Part of the problem if your to T which allows the cast to Option<Int>, which in turn unifies with EnumValue. I'm not sure right now how we could tame this.

This properly fails at compile-time now.
