fun composeErrors(first: Throwable, other: Throwable?): Throwable
fun composeErrors(all: List<Throwable>): Throwable?

Composes multiple errors together, meant for those cases in which error suppression, due to a second error being triggered, is not acceptable.

On top of the JVM this function uses Throwable#addSuppressed, available since Java 7. On top of JavaScript the function would return a CompositeException.
