Operator

# <=(_:_:)

Returns a Boolean value indicating whether the first tuple is ordered before or the same as the second in a lexicographical ordering.

`lhs`

An empty tuple.

`rhs`

## Discussion

An arity zero tuple is always before or the same as another arity zero tuple in a lexicographical ordering.
