I’ve experimented with method design at various times and place notation is a very useful tool, but it’s lacking in some situations. Here’s a few ideas for some bolt-ons.

In which your hopeful protagonist describes Million Point Sculptures, and a highly interactive exploration tool written in Metal.

In the 1980s there was a wave of fascination with fractals and chaos in popular culture, and several books really caught the imagination of young me.

One was Chaos by James Gleick (un classique)¹. Also there were some lovely books by Clifford Pickover, like Computers and the Imagination, containing curious things like Million Point Sculptures: intriguing generated art showing wispy smoke-clouds. They’re generated by some quite simple equations.

I’ve been using the Swift Testing framework more. Despite my previous grumble I do like the arguments: feature of the @Test macro and how much it can clean up tests:

@Test(arguments: [
	(true, "bob", 38),
	(false, "sue", 45)
])
func testUserPermissions(isBasketEmpty: Bool, username: String, age: Int) {
    #expect( ... )
}

The ability to supply a list of parameter variants to test is very useful. I think it tends to result in more exhaustive tests because of ease of use.

But being able to easily whack in a list of argument variants soon reveals a slight annoyance. It’s not unusual to end up with a test like this:
