d3.sort, but with an accessor (length = 1) instead of a comparator.

[mbostock]

It’d be nice if this

d3.sort(array, d => d.value)

were shorthand for this

d3.sort(array, (a, b) => d3.ascending(a.value, b.value))

though where the accessor is only evaluated once (in case of non-determinism). We already do something similar for d3.bisector so this seems reasonable!
