The arguments scope is copied into the local function scope after the
cfargument tags, so all arguments are also in the local var scope.
You can see this in action with the following code:
<cffunction name="test">
<cfargument name="testvar" type="string" default="I'm an argument"
/>
<cfdump var="#arguments#" label="Arguments scope" />
<cfdump var="#getPageContext().getActiveFunctionLocalScope()#
label="Function local scope" />
<cfoutput>Initial Argument value: #arguments.testvar#<br
/></cfoutput>
<cfset testvar = "I'm a local variable" />
<cfoutput>
local variable value: #testvar#<br />
argument value: #arguments.testvar#<br />
</cfoutput>
<cfset arguments.testvar = "I'm a modified argument value" />
<cfoutput>
local variable value: #testvar#<br />
argument value: #arguments.testvar#<br />
</cfoutput>
<cfdump var="#arguments#" label="Arguments scope" />
<cfdump var="#getPageContext().getActiveFunctionLocalScope()#
label="Function local scope" />
</cffunction>
<cfoutput>
#test()#
</cfoutput>
