 This will disable all parallelism in the linker (expect significant slowdown).

+Because `js.UndefOr` is implemented differently in Scala 3, implicit conversion to `js.Any` was not available.
+
+Thanks to @armanbilge, `js.UndefOr[T]` now implicitly converts to `js.Any`, provided `T` is convertiable to `js.Any`.
+
+For example, the following now compiles on Scala 3:
+
+{% highlight scala %}
+val x: js.Any = js.defined("")
+{% endhighlight %}

 The compiler and linker now use `@inline` / `@noinline` hints provided at the call-site.
 See the [Scaladoc for `@inline`](https://www.scala-lang.org/api/2.13.11/scala/inline.html) for details.
