Is join('') awful? It has its uses, along with an identity when you know
a string has no non-BMP chars encoded as pairs):
s.split('').join('') === s
Now and then, split('') followed by array processing followed by
join('') works best.
Also, building an array and then doing a.join('') to get a string used
to be a perf win over +-based string concatenation in IE, at least.
