Not at all. I don't know of any problems in ie5.5 or earlier, but I've had
problems with getting 1 and 0 to evaluate to true and false when returning
them from a function in IE6. The script worked with true and false but not
1 and 0. (Event was not canceled when 0 was delivered, even though it
worked with delivering 0 in a less complicated chain of functions.)

My guess at the reason for this behavior is that IE6 somehow turned it into
a string, but since I've not checked it's typeof value I don't really know.
