Lambdas: Writing a lambda

x => x * 2
(a, b) => a + b
msg => {
    debug(msg)
    msg.len()
}

fn main() {
    const double = x => x * 2
    print(double(21))
    const prices = [120, 40, 300]
    print(prices.map(p => p + 10))
    let limit = 10
    const over = n => n > limit
    limit = 0
    print(over(5))
}
