Runs the fallback branch when preceding conditional branches do not match.

# =============================================================================
# अन्यथा — Runs the fallback branch when preceding conditional branches do not
# match.
# =============================================================================
#
# What this teaches:
#   • Conditional fallback — `अन्यथा` provides the else/otherwise branch that
#     runs when no preceding `यदि` or `अन्यथायदि` condition matched
#   • Always comes last in an if-else chain; takes a block body
#
# Common mistakes:
#   • Writing `अन्यथा यदि` instead of the canonical `अन्यथायदि` for else-if branches — `अन्यथा` must always be final.
#
# See also: यदि, अन्यथायदि
# =============================================================================

# अन्यथा — final else branch
#
# GRAMMAR:
#   elseClause :← 'अन्यथा' block
#
# EXPECTED OUTPUT:
#   Scalar stdout smoke (see body).

# BACKEND:

# =============================================================================
# अन्यथा — Runs the fallback branch when preceding conditional branches do not
# match.
# =============================================================================
#
# What this teaches:
#   • If-else branches — `यदि { } अन्यथा { }` provides two-way branching; exactly
#     one arm executes
#   • `अन्यथायदि` chains additional conditions before the final `अन्यथा` fallback;
#     first match wins
#
# Common mistakes:
#   • TODO: placing `अन्यथा` before a `अन्यथायदि` branch — `अन्यथा` must always be the
#     final clause
#
# See also: यदि, अन्यथायदि
