Nice to see that I've started an interesting debate :) I actually agree 
with both of you, but I have always felt that the most annoying part of 
ColdFusion was not being able to just call a function without having to use 
a <cfscript> block or something silly like <cfset temp = SomeFunction()>. 
So, in rebellion, I lean towards using <cfset> in the "improper" way.
