In a type system without subtyping, I think it might be possible to express the type using an existential type—something like this, in pseudo-Haskell syntax: 1 cmpToKey :: (a -> a -> Bool) -> exists b. Ord b => (a -> b) This isn’t actually a legal Haskell type signature,...
Pure functional languages like Haskell are different from imperative languages like C, or Java in that, a pure functional program is not necessarily executed in a specific order, one step at a time. A Haskell program is more akin to a mathematical function, in which you may solve the "equat...
Similarly, if we recompile an android_library due to a dependency change, but the resulting classes are identical, we don't need to re-run the DEX compiler (dx). The determination about whether to rebuild is based on the value of an additional key: an input-based key, which is ...
So one can take the current Ethereum code base, whether in Rust, or Go, or Haskell, and run it as a ABCI application using Tendermint consensus. Indeed, we did that with Ethereum (opens new window). And we plan to do the same for Bitcoin, ZCash, and various other deterministic ...
Haskell: A direct port of the original tutorial. Python: One such port follows the tutorial closely, while the other is a more ambitious rewrite with an interactive command line. Both of those use llvmlite as the bindings to LLVM. Rust and Swift: It seemed inevitable we’d get po...
The first problem is that of course not every type needs to have a name; C# 3 has anonymous types which have no names by definition. Is "string[][]" the name of a type? What about "List<string[][]>" -- does that name a type? Is the name of the string type "string"...

There are certainly many small problems with GHC's Template Haskell support, but I would say that there is one fundamental design point which Racket got right and Haskell got wrong: Template Haskell does not sufficiently distinguish betweencompile-timeandrun-timephases. Confusion between these two ...
You don't even think about it, like in Haskell. Whereas memoizing is something you do specifically to a function as a way to optimize it.Like I said, this is a property of pure functions. I want to talk about why I don't like this term just a little bit....
