Default Parmeter pass through

It would be nice if the Defaultiness of optional parameters was passed through to functions called by a function with a default parameter. For instance with this code

function Func1([defParm])
 variable defParm
 return func2(defParm = defParm)
end
function Func1WorkAround([defParm])
 variable defParm
 if (ParamIsDefault(defParm))
 return func2()
 else
 return func2(defParm = defParm)
 endif
end
function Func2([defParm])
 variable defParm
 if (ParamIsDefault(defParm))
 print "Default"
 return 0
 else
 print "Not Default"
 return 1
 endif
end

You get the following results

•func1()
 Not Default
•func1WorkAround()
 Default
•func1(defParm=1)
 Not Default
•func1WorkAround(defParm=1)
 Not Default

The workaround works fine, but when you start to have multiple default parameters it gets cumbersome
