I disagree - Any is far _too_ ambiguous.  Also, as far as ambiguity, all
values in a user-submitted FORM struct are cast as simple types (strings).
Allowing the use of "Any" opens up your code to all kinds of scary
validation errors.  I could pass in an array, a Struct, a java object, a COM
object, or a CFC if I wanted to.  In fact, if I was just looking at the
signature for your code, I might think that I _could_ pass in any of those,
since Any allows that.  That's a contract violation.  Even if your
validation routine checks IsDate() or IsString() (or something to that
effect), what's the point of allowing objects to be passed in the first
place then?

I would always use the most restrictive type that can be allowed for these
types of validation routines.  In this case, that is a string.  All dates
can be represented by a string - especially in CF.
