# =============================================================================
# ถ้าไม่ก็ — Adds an else-if branch after a previous ถ้า branch.
# =============================================================================
#
# What this teaches:
#   • Else-if chains — `ถ้าไม่ก็ <condition> { body }` adds intermediate conditional
#     branches between `ถ้า` and `มิฉะนั้น`
#   • First match wins: evaluation stops at the first `ถ้า` or `ถ้าไม่ก็` whose
#     condition is `จริง`
#
# Common mistakes:
#   • TODO: forgetting that `ถ้าไม่ก็` blocks are skipped once a preceding branch
#     matches
#
# See also: ถ้า, มิฉะนั้น

# ถ้าไม่ก็ <cond> { }
# มิฉะนั้น { }
#
# GRAMMAR:
#   ifStmt :← 'ถ้า' expr block ('ถ้าไม่ก็' expr block)* ('มิฉะนั้น' block)?
#
# EXPECTED OUTPUT:
#   Afternoon (hour=14 matches first ถ้าไม่ก็ branch).

# =============================================================================
# ถ้าไม่ก็ — Adds an else-if branch after a previous ถ้า branch.
# =============================================================================
#
# What this teaches:
#   • Standalone else-if — `ถ้าไม่ก็` provides an intermediate conditional branch
#     evaluated only when the preceding `ถ้า` condition was `เท็จ`
#   • Chains: `ถ้า { } ถ้าไม่ก็ { } มิฉะนั้น { }` for multi-way branching
#
# Common mistakes:
#   • Writing `มิฉะนั้น ถ้า` instead of the canonical `ถ้าไม่ก็` for else-if branches.
