Idea

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.

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