Unfortunately, that's just life... Certain tags and functions require that a variable be passed by name (<cfloop query=>, <cfoutput query=>, isdefined() for example) while others require that they be passed by reference (<cfdump var=>, <cfloop collection=>, etc.). Remember #ParameterExists()#? Did the same thing as isDefined() only you passed object references rather than names...
