WWDC - Generics and some Algorithms

[[)roi(]]

Two interesting presentations at WWDC:

• First one is about building solutions with Generics
• Second one also touches on generics but ties it in with algorithms centred on this theme:

"If you want to improve the code quality in your organisation, replace all of your coding guidelines with one goal..."

No Raw Loops

[td]Note:

• Sean Parent's quote comes from his 2013 Channel 9 C++ presentation, entitled C++ seasoning.
• This btw is a very common theme in functional programming; where the goal is always to avoid explicit iteration with loops; both to secure the computation and to make code far more descriptive.
• Even though the presentations are Swift centric; the central concepts and algorithms are universal, and hence should translate fairly easy to most languages.

Lol. Raw loops. No 1 reason for code review pushback where I work.

As it should be....because most programmers generally suck at writing code that is more performant than that available in e.g. STL, stdlibs, etc...

...IMO this should be extended to all loops, non compositional code and the majority of stateful / effectual code, because not only are they more difficult to GROK vs. declarative code, they usually are like raw loops another source of bugs, and hardly ever sufficiently justify the effort, and the added complexity of trying to provide 100% test coverage for it.
