It's not a statement, it's an operator; and functions have far more
overhead than direct operators. There's little benefit in making 'is'
into a function, and high cost; unlike 'print', whose cost is
dominated by the cost of producing output to a console or similar
device, 'is' would be dominated by the cost of name lookups and
function call overhead.
