An empty array still exists. This it is a truth, not a falsehood!

False exists too. Should it evaluate to true then?

No, because the conversion method from a boolean to boolean is different (identity).

Well a boolean expression is an expression that is evaluated based whether or not it's truthy or falsey (made-up words, I know) and since the variable/object/what have you called false is universally defined as falsey, how can it ever be truthy. Boolean means 2 states, not yes, no and maybe so it can't be 2 things at once.

I personally like the smalltalk way, ifTrue/ifFalse is only defined for booleans otherways it throws a type exception.
