Fair enough. I had considered the case where variables in your function might overwrite other variables in the page, but had figured people should know better to have multiple variables on the same page with the same name. Of course, who's to say the UDF couldn't have been written by a different programmer and cfincluded in a library of other functions. Then all of a sudden it would be much easier to get unintentional overwriting of variables. Color me convinced. :)

This other silly example demonstrates why (run in a single template): <cffunction name="foo"> <cfset i = 100> <cfreturn 'bar'> </cffunction> <cfoutput> <cfset i = 1> <cfloop condition="i LT 10"> <cfset bar = foo()> #i#<br /> <cfset i = i + 1> </cfloop> </cfoutput> You'd expect the loop to loop 10 times but it doesn't. Var that variable in the function and it does.
