[thelist] CF: using a back reference to address a struct?

[Mark Mandel]

>From looking at it, you're trying to do a loop with only one line of code,
which, without closures is going to be pretty tricky.

I would just do it as (this is typing on the fly, so you may get some
errors):

<cfloop collection="#filter#" item="key">
   <cfset text = replaceNoCase(text, "[" & key & "]", filter[key]) />
</cfloop>

And be done with it.

You could get fancy and use a StringBuffer/Builder if you wanted to, but for
the number of lines of text, it may not be necessary.
