Who needs this particular consistency anyway?
Users generally benefit from this kind of consistency; we hear
complaints about reduce/reduceRight.
People seem to have survived reduce/reduceRight.
The perf savings is an allocation
Do engines allocate each time when a function expression is used as

If so, .bind doesn't cost more than a function expression.
