Hello!

This is the current Lemmy equivalent of https://www.reddit.com/r/ProgrammingLanguages/.

The content and rules are the same here as they are over there. Taken directly from the /r/ProgrammingLanguages overview:

This community is dedicated to the theory, design and implementation of programming languages.

Be nice to each other. Flame wars and rants are not welcomed. Please also put some effort into your post.

This isn't the right place to ask questions such as "What language should I use for X", "what language should I learn", and "what's your favorite language". Such questions should be posted in /c/learn_programming or /c/programming.

This is the right place for posts like the following:

See /r/ProgrammingLanguages for specific examples

A design that subsumes the various syntactic forms of

  • if statements/expressions
  • switch on values
  • match on patterns and pattern guards
  • if-let constructs

and scales from simple one-liners to complex pattern matches.

A quite decent syntax and an excellent domain name!

Good catch, that should have been if person in the first line.

It's been a left-over from when syntax looked like this:

  is Person("Alice", _)$person then "{$person.age}"
  is Person("Bob", $age)       then "$age"

This looks very similar to The Ultimate Conditional Syntax, although that's for ML so it doesn't have the nice syntax for chaining method calls.

The author of that paper hung around in the lang design forum were I originally presented this.
