I think that I missed this in the docs. It seems that you can chain
set variables
cfset a=1
cfset c=b=a+1
This will give you a=1, b=2, c=2.
On a related note, the following will fail
cfset a=1
cfset c=b+1=a+1
The chain works as long as there is no operation except on the
right-most item in
A quick test indicates it's new in CF9. Worth mentioning that it is
NOT treating the assignment as an expression, it is only allowing
multiple variables to be assigned to a single expression. Your second
test case would fail regardless of which one CF was doing, but this
example also fails
6.1 doesn't like it...

I've just run a regex against the cfdocs and I can't find any
reference to this new chaining functionality. This implies it's a new
and overlooked functionality. I wonder what else is un-noted.
Assignments in loop conditions has been around for a while. If it's a
CFLoop then you can only alter
It was definitely added in CF9 but you are right, I don't see it
listed in What's New in Coldfusion 9. Curious.
This is the reference page for this particular functionality however:

Not only did I miss it, my regex didn't find it because it assumed a
cfset. There are a few things not mentioned in the what's new
section. This is only one of them. :(
