In CFC, I always do this: <cffunction name = "something"> <cfargument name="some" required="true" type="string"/> <cfset var few = arguments.some/> <cfset few = 10/> </cffunction>
If we should always scope our variables. Should I do this? <cfset var variables.few = arguments.some/> <cfset variables.few = 10/> The reason I re-set arguments.some to few is because I want to type 3 letters instead of 14, but if I should always scope my variables, then there is no point of resetting it.
