# What this teaches:
#   • Primitive types logic, trống, and chưa_biết.
#   • Related keywords: đúng, sai, hàm, ∷, trống
#
# Common mistakes:
#   • Using `chưa_biết` where a concrete type is expected — `chưa_biết` is the dynamic dispatch type; use `là` checks or match before extracting.

fn ping() → void {
    print "primitiva smoke"
}

fn describe(any value) → string {
    if value is none then return "nihil est"
    return "aliud est"
}

fn describe_boolean(bool value) → string {
    if value ≡ true then return "verum est"
    return "aliud est"
}

main {
    ping()
    print describe(null)
    print describe_boolean(true)
    print describe(42)
}

Expected output:

primitiva smoke
