// This is a Conlang file.
// This is a function. It can be called with the call operator.
// The function called `main` is the program's entrypoint
fn main() {
// An if expression is like the ternary conditional operator in C
let y = if 10 < 50 {
"\u{1f988}"
} else {
"x"
};
// A `while` expression is like the while-else construct in Python,
// but it returns a value via the `break` keyword
let z = while false {
// do a thing repeatedly
break true
// If `while` does not `break`, fall through to the `else` expression
} else {
false
};
// The same is true of `for` expressions!
let w = for idx in 0..100 {
if idx > 2 * 2 {
break idx
}
} else {
12345
};
// A block evaluates to its last expression,
// or Empty if there is none
(y, z, w) // (🦈, false, 5)
}
