Empty and logical expressions

[dunbarx at aol.com]

Hi.


If we are not talking about numbers, the ">" operator will compare the ascii values of the two arguments. "0" has ascii 48. Empty, though has ascii, well, empty.



 I suppose that 48 > nothing.

I just ran down a bug because.....

(empty<0) evaluates to true. I would have thought empty is only equal to
empty(or "") and any other logical test would be false.

Is this common knowledge or did I miss something in the docs?
