Sum Types Are Coming (2015)
Just as all mainstream languages now have lambda functions, I predict sum types are the next construct to spread outward from the typed functional programming community to the mainstream. Sum types are very useful, and after living with them in Haskell for a while, I miss them deeply when using languages without them…

The Value of Undefined Behavior
In several places, the C and C++ language specifications use a curious, and fairly controversial, phrase: undefined behavior . For certain program constructs, the specification prescribes no specific behavior, instead allowing anything to happen . Such constructs are considered erroneous, and so the result depends on…

Union Types in Flow and Reason
Union types are powerful yet often overlooked. At work, I've been using Flow which thankfully supports union types. But as I've refactored more of our code to use union types, I've noticed that our bundle size has been steadily increasing!

Clojure Don’ts: Lazy Effects (2015)
Laziness is often useful. It allows you to express “infinite” computations, and only pay for as much of the computation as you need.

Crafting Interpreters: Strings
“Ah? A small aversion to menial labor?” The doctor cocked an eyebrow. “Understandable, but misplaced. One should treasure those hum-drum tasks that keep the body occupied but leave the mind and heart unfettered.”

Representing the Impractical and Impossible with JDK 10 “var”
Having benefited from “var” for many years when writing c#, I’m delighted that Java is at last getting support for local variable type inference in JDK 10. From JDK 10 instead of saying ArrayList<String> foo = new ArrayList<String>(); we can say var foo = new ArrayList<String>(); and the type of “foo” is inferred as…

Haskell’s State monad is not a monad (2014)
Haskell’s State monad has a shameful secret. It’s not a monad [ State monads don’t respect the monad laws in Haskell, Simon Marlow ] . Look:

Value Type Hygiene
Briefly put, types in L-world are ambiguous, leading to unhygienic mixtures of value operations with reference operations, and uncontrolled pollution from null s infecting value code.

On Competing with C Using Haskell (2017)
Mark Karpov wrote in his article on Migrating text metrics to pure Haskell how he originally did foreign calls out to C for many of the functions in his text metric package, but now ported them to Haskell when he learned that Haskell can give you performance comparable to C.

October 1997: It has been six years since I finished Paradigms of AI Programming (or PAIP ), and now seems like a good time to look back at how Lisp and AI programming have changed.
