Alright I’ve built them into the language. Here’s the example code using what you asked for, as far as I understand at the moment:
class Person {
init(name, age) {
this.name = name
this.age = age
} func doesNotUnderstand(method, args) {
"Person " + this.name + " does not have " + method
}
}func greet(person: Person) {
match person {
{name: "Alice", age: 30} => "Hi Alice, you're 30."
{name, age} if age > 18 => "Hi " + name + ", you're an adult."
_ => "Hello there!"
}
} macro log_call(func) {
`(println("Calling " + ${func}))
} let alice = new Person("Alice", 30)
log_call(greet(alice)) # Expands to println and calls greet |
