Marks a function as able to throw along a recoverable channel.

# =============================================================================
# يرمي — Marks a function as able to throw along a recoverable channel.
# =============================================================================
#
# What this teaches:
#   • the `يرمي` modifier on function declarations — marks a function as throwable
#   • the `⇥` error type annotation for specifying the error type contract
#
# Common mistakes:
#   • Forgetting to declare the ⇥ error type — يرمي requires an explicit ⇥ error type in the function signature.
#
# See also: ارم, التقط, ⇥, مخطئ, ثابتة
# =============================================================================

# meta/iacit — throwable function modifier
#
# GRAMMAR:
#   funcModifier :← 'يرمي'
#
# EXPECTED OUTPUT:
#   يرمي surface declared
#
# BACKEND:
#   Prefer explicit ⇥ error types for callable contracts; see ارم/functio-fallibilis.fab.
