Those 5+ implementations are already there, and already work.
A 6th implementation to replace known working code is just churn
unless it provides some additional value. Making the code "better"
does not itself add value.

I do use and enjoy all of these implementations! Thank you
for the fine implementations. In the end, if you're maintaining
the code it's your call. I question change that does not have
an obvious purpose because statistically every 10th change has
a bug.

Now that I know what the change is for I am fine with it. I
like seeing reasons up front.
