Callable posture for asynchronous finite functions.

# =============================================================================
# 异步 — Asynchronous finite callable posture
# =============================================================================
#
# What this teaches:
#   • Preferred async posture word after the parameter list: `异步 → T`.
#   • Return type is observed as `期约<T>` at call sites.
#   • Consume with `等定`, `等变`, `等返`, or `等弃`.
#
# Common mistakes:
#   • Using bare `让出` to await — await is not yield; use await morphology.
#
# See also: 未来, 期约, 等定, 等弃
# =============================================================================

# GRAMMAR:
#   callablePosture :← '异步'
#
# EXPECTED OUTPUT:
#   42

函数 responde() 异步 → 整数 {
    返回 42
}

异步入口 {
    等定 _ responsum ← responde()
    显示 responsum
}

Expected output:

42
