Pedantry can be dangerous. While Len returns an integer, CF treats non-zero integer values as boolean "true" values when they're used in boolean expressions. Now, you may argue that your explicit syntax is more readable, but I'd counter that by saying that any competent CF developer should know that integers are treated as boolean values.
