Classes in Atoms lose their functions after modification

Due to the way setKey is written, the original prototype is forgotten. This means all of the functions disappear as well.

Lines 7 to 19 in 281b70f

	export function setKey<T, K extends keyof T>(k: K, v: T[K], o: T): T {
	if (k in o && structEq(v, o[k])) {
	return o
	} else {
	// this is the fastest way to do it, see
	// https://jsperf.com/focal-setkey-for-loop-vs-object-assign
	const r: { [k in keyof T]: T[k] } = {} as any
	for (const p in o) r[p] = o[p]
	r[k] = v
	return r
	}
