Yes, but this still requires knowing if your variable
is a date or not. A
straight primitive == would not. To test for that would only be 2 extra
lines of code but it's still a special case that you have to put everywhere.
My point is only that having to treat Dates differently from Numbers and
Strings and use functions for comparison is inconvenient, no matter how
simple it actually may be. This could be improved by making them (or a new
class) a primitive.
Of course if a future version of ActionScript allows users to override
operators in custom classes, I can create my own [primitive-like] Date
class. Then no-one will have to hear me complain. :)

Hi Kelly,
For simple comparisons there is are compare() and dateCompare() functions
in
the mx.utils.ObjectUtil class.
