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

What would be actually useful is a package called is-prime.

Unfortunately, its usefulness would be obscured by the proliferation of
packages like is-even, is-odd, and others of their ilk.  Just like
comments that repeat what the code already says, thereby obscuring the
actual intent of the code while giving an illusion of being
well-documented.

	/* Look, Ma! I'm so well-documented! */

	// loop from 0 to len
	for (i = 0;		// set i to zero
		i < len;	// check that i is less than len
		i++)		// increment i
	{
		if (i & 2) {	// if bit 0 is non-zero
			writeln("How odd!");
		} else {	// otherwise
			writeln("But even so...");
		}
	}

Blecch.
