its a little screwy inside of a <cfoutput query=""> loop
If you are pushing to the output stream query takes top spot but if
you are inside of a cfset variables (maybe arguments) takes top spot.
Its a little wacky so its always good to just scope your variables.
As for performance its worth mentioning that isdefined("url.bob") will
still search other scopes so using structKeyExists is a better option.
This has been discussed before but figured I'd throw in that reminder
since its on my mind today (form validation fun!).
