Compatibility annotation for asynchronous posture.

# =============================================================================
# भविष्य — Compatibility annotation for asynchronous posture
# =============================================================================
#
# What this teaches:
#   • Preferred async posture — write `async` for a finite async function.
#   • Compatibility annotation — `@ भविष्य` remains accepted and preserved as
#     the legacy spelling for async posture.
#   • Related keywords: संकेतक, रुको_स्थिर, रुको
#
# Common mistakes:
#   • Calling an async function and forgetting to consume the वादा with
#     `रुको_स्थिर`, `रुको_चर`, `रुको_लौटाओ`, or `रुको`.
#
# See also: संकेतक, रुको_स्थिर, रुको
# =============================================================================

# @ भविष्य — compatibility async function annotation
#
# @ भविष्य
# फलन नाम(…) → प्रकार { … }
#
# GRAMMAR:
#   annotatedFunc :← '@' 'भविष्य' funcDecl
#   callablePosture :← 'async'
#
# EXPECTED OUTPUT:
#   none — Rust async runtime whitelist (compile-only in harness)
#
# BACKEND:
#   Rust async runtime not linked in exempla harness (whitelist: भविष्य/futura.fab).

@ future { }
fn responde() → int {
    return 42
}

async_main {
    # रुको_स्थिर awaits the वादा and binds the resolved value
    await_const int responsum ← responde()
    print responsum
}

Expected output:

42
