No I didn't found it anywhere, and up until now I haven't found any article that discuss this "odd" behaviour (althoug it realy isn't so odd after all...). As I said, even Steven Feuerstein was not avare of that.

But I haven't discovered this all by myself either! Once my DBA/developer mate asked me if the condition

IF sysdate = sysdate THEN ...

allways results in TRUE. Without even thinking any further I immediately confirmed this. But my friend being a suspicious soul, wanted to be absolutely sure and by testing it in "supposed-to-be" an infinite loop discovered that I was wrong.
