I had the same question few months ago. See below the answer from Josh
Rosenbaum.
The thread was called: "detect the reference of a variable in TT"
----------------
One way is to use vmethods that are only associated with certain types.
ie: to detect a
*) hash use .keys and see if it returns a number.
*) scalar: length
You could roll your own ref vmethod or pass a routine via vars to do it.
This has been discussed before a few times on the list. It almost
should be in the main distribution even though I know the idea is to
keep knowledge of that type of thing away from the user. I certainly
wouldn't mind seeing it in the main distribution, though.
