Further Advances in Objective-Swift
Previously on SICPers, I defined objects as functions that return methods and built dynamic method dispatch in this object system. It’s time to tie up some loose ends. Proper selectors In languages like Smalltalk and Objective-C, an object’s range isn’t … Continue reading

Dynamic Method Dispatch in Object-Oriented Programming in Functional Programming in Swift
In the previous episode, I said that objects are functions that map their ivars onto methods. However, the objects that I demonstrated in the post were tables, structures of functions that closed over the ivars, like this: struct List<T> { … Continue reading

Object-Oriented Programming in Functional Programming in Swift
The maths behind functional programming predates computers. Once people had some experience with both of these things, they stripped them down and created object-oriented programming. It’s still possible to jettison a lot of the features of functional programming and work … Continue reading

I agree with this, programming is not a craft by Dan North. So here’s my concern with the idea of Software Craftsmanship. It’s at risk of letting programmers’ egos run riot. And when that happens… well, the last time they … Continue reading
Did that work? Maybe.
A limitation with yesterday’s error-preserving approach is that it leaves you on your own to recover from problems. Assuming your error definitions are sufficiently granular, this should be straightforward but tedious. Find out what went wrong, recover from it, then … Continue reading
