10 years ago, I thought "programming is too hard, I'll make tools to make it easier" 5 years ago, I thought "I'll make a new language to make it easier" now I'm working on tools to make "making new languages" easier 😂

@meekaale that is certainly one definition of coherent

@georgesboris in the languages I'm familiar with, "fallthrough" bypasses the "checking" part, and just goes to the body of the next case. This makes sense for simplistic, non-pattern-matching switch because it's impossible to have multiple cases that could match the same value.

@vpatryshev hm do you anything more specific? The first repo I found by John Pretty has an 80-line method (I may have found the wrong John Pretty)

@rtfeldman wowww that sounds super cool! In the post you don't address "why not self-host" but it sounds like it's a "Roc is still changing in fundamental ways" thing?

@rawdeg ooh fancy

@vpatryshev More seriously though; do you have a codebase you can point me to that exemplifies your ideas of "good code"? I'd be interested to read through it.

@BenjaminPrevor that is fascinating

@rawdeg Does C#'s switch allow pattern matching on algebraic data types? (this language feature only really makes sense in the context of a powerful switch)

@vpatryshev consider whether your advice could be used to argue against all modern language features

@georgesboris Guard clauses are cool, but are strictly less powerful than what I'm proposing. Here's maybe a better example to indicate why:

@samth nice!

@iamwil hmmm I actually don't think you could? Like koka wouldn't allow you to "resume evaluation of this `match`, but ignore the first case"

@mholt6 presumably "being allowed to protest" is a necessary precondition for whatever the goal of the protest is, so "the police are letting us protest" is a preliminary win?

RT @kentcdodds: I'm stoked to have @jaredforsyth at #EpicWebConf in March! He’ll be diving into type inference and programming languages in…

would you believe that this is normal game of life, with a slightly different display?

@TodePond imagine, conway's game of life, but, hexagons (the rules are the same, cells still have 9 neighbors, every other row is just shifted over a bit. it's a display-only change)
