# อื่น — Starts the default branch of an เลือก or แยก statement.

#
# What this teaches:
# • Default arm — `อื่น <block>` is the catch-all branch in an `เลือก`
# or `แยก` match expression
# • Fallback handling — when no `กรณี` pattern matches, execution falls
# through to the `อื่น` block
#
# Common mistakes:
# • using `อื่น` with `แยก ทั้งหมด` — `ทั้งหมด` forbids catchall arms and requires listing every variant explicitly (SEM044)
#
# See also: เลือก, แยก

# อื่น — default เลือก arm
#
# GRAMMAR:
# defaultClause :← 'อื่น' block
#
# EXPECTED OUTPUT:
# Scalar stdout smoke (see body).
