# What this teaches:
#   • Declares the asynchronous program entry point.
#   • Related keywords: आरंभ, रुको_स्थिर, रुको
#
# Common mistakes:
#   • Calling a `async` function without consuming its वादा; use
#     `रुको_स्थिर`, `रुको_चर`, `रुको_लौटाओ`, or `रुको` inside an `आरंभasync`.

# आरंभasync — async program entry point
#
# आरंभasync { <body> }
#
# GRAMMAR:
#   asyncEntry :← 'आरंभasync' block
#
# EXPECTED OUTPUT:
#   none — Rust async runtime whitelist (compile-only in harness)
#
# BACKEND:
#   Pairs with `async` and awaited bindings; contrast with आरंभ
#   (synchronous entry).

# Helper async finite function
fn accipe() async → string {
    # Simulates async finite operation
    return "datum paratum"
}

fn metire(string datum) async → int {
    return datum.length()
}

# Futura entry point
async_main {
    print "incipiet initium"

    # Await async functions with रुको_स्थिर
    await_const string datum ← accipe()
    print "acceptum: §"(datum)
    await_const int longitudo ← metire(datum)
    print "longitudo: §"(longitudo)
    print "opus perfectum"
}

Expected output:

incipiet initium
acceptum: datum paratum
longitudo: 13
opus perfectum
