food for thought - swift 5 released - bottom types, string interpolation, and stuff.

This is a non-sequitur, the fact that some compilers produce 
different assembly does not say anything about how well the 
functions convey intent.

However, in general, knowing that the bit-twiddling variety of a 
function produces different code to the mathematically precise 
expression, would just make me stop and think twice, three or 
even four times if just perhaps, it's better to stick to the 
mathematically precise and clear rendering of the desired 
algorithm.
