Referencing Attributes of an Attribute

Hello,

Is there any way to reference the (for lack of a better word)
"subattributes" of a variable ? For example, I define variables
"a" and "b" below, where both have attributes and "b" is added
to "a" as an attribute.

I was hoping to be able to reference these "subattributes" via
a_at_extra@name, or (a_at_extra)@name, etc.

Thanks, Bruce

ncl 0> a=2
ncl 1> a_at_name="one"

ncl 2> b=4
ncl 3> b_at_name="two"

ncl 4> a_at_extra=b

ncl 5> print(a_at_extra@name)
fatal:syntax error: line 5 before or near @name
print(a_at_extra@name
-----------------^

fatal:error in statement
ncl 6> print((a_at_extra)@name)
fatal:syntax error: line 6 before or near @name
print((a_at_extra)@name
-------------------^

fatal:error in statement
