ColdFusion local scope inside object literal

Question

I'm seeing some weird behaviour when using CF's local scope in an object literal, in function arguments. But only when executed inside a loop...

Example code:

<cffunction name="f">
    <cfoutput>
        <cfset LOCAL.foo = 123 />       

        <!--- Works fine --->
        #serializeJSON({blah = LOCAL.foo})#

        <!--- Works fine --->
        <cfloop from=1 to=1 index="i">
            <cfset bar = {blah = LOCAL.foo} />
            #serializeJSON(bar)#
        </cfloop>

        <!--- Element FOO is undefined in LOCAL --->
        <cfloop from=1 to=1 index="i">  
            #serializeJSON({blah = LOCAL.foo})#
        </cfloop>
    </cfoutput>
</cffunction>


<cfset f() />

PS: serializeJSON() is just for example purposes. This is happening in any function I've tested where one of the arguments is a struct.

Works just fine in Railo.

It also doesn't make any difference if using any other container instead of local scope, also it's impossible to catch this with cftry.

If you serialize just local scope within the loop:

<cfloop from=1 to=1 index="i">
    #serializeJSON(local)#
</cfloop>

Result is:

{"ARGUMENTS":{},"___IMPLICITARRYSTRUCTVAR1":{"BLAH":123},"___IMPLICITARRYSTRUCTVAR0":{"BLAH":123},"FOO":123} 

Looks like a bug. Mind filing?
