Adds an else-if branch after a previous إذا branch.

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

# GRAMMAR:
#   ifStmt :← 'إذا' expr block ('وإلاإذا' expr block)* ('وإلا' block)?

# EXPECTED OUTPUT:
#   Afternoon (hour=14 matches first وإلاإذا branch).

Adds an else-if branch after a previous إذا branch.

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

# وإلاإذا — else-if branch

# GRAMMAR:
#   elseIfClause :← 'وإلاإذا' expr block

# EXPECTED OUTPUT:
#   Scalar stdout smoke (see body).
