Yields one value from a generator.

# =============================================================================
# nhường — Yields one value from a generator.
# =============================================================================
#
# What this teaches:
#   • Yield — `nhường <expression>` emits one item from a `sinh` or `async_sinh`
#     callable
#   • Async values use `đợi_hằng`, `đợi_biến`, `đợi_trả`, or `đợi_bỏ`; `nhường`
#     is not an await form
#
# Common mistakes:
#   • using `nhường` outside a generator body
#
# See also: con_trỏ, sinh, async_sinh
# =============================================================================

# nhường — yield from a stream function
#
# hàm stream() sinh → T { nhường value }
#
# GRAMMAR:
#   yieldStmt :← 'nhường' expr
#
# EXPECTED OUTPUT:
#   [1, 2]
#
# BACKEND:
#   Cursor stream materialization smoke.
