Well, in a sense.
but what about
methodName(arg1)
where arg1 = any

Still valid....
Believe it or not, I strongly believe coldfusion needs to be more
typecast.. And grow up to be more of a great language. it would be so
damn nice...

we're
using a dynamically typed language. I kind of like that =).
