Barney,
I'm curious - why do you prefer structKeyExists() vs. setting
default values?

If you use positional parameters, only parameters at the end can be
left off. However, you can use named parameters without using

The third argument is not required but this will throw an error. This
situation doesn't arise when you use cfinvoke as you can simply miss out
the cfinvokeargument tag.

Another alternative is to use named arguments.
cfset result = obj.testmethod(foo=0,bounce=1,boing=10)
assuming your function is defined as:
cffunction ...
cfargument name=foo...
cfargument name=bar...
cfargument name=boing...
cfargument name=bounce...

If they are numeric arguments, you shouldn't have an empty string as
the default.
As other have hinted, specify required=false but do not specify a
default= value.
Then you can test
