You could look at the path of the object, with
18!:2 Obj
Since the path is under the control of the user, you would have to know
what you do with the path to be able to make sense of it. Often, the
first atom in the path would tell you what you are looking for.
An object (called a 'numbered locale' in the J docs) is not a boxed
integer: it's a boxed string that contains all numberics. You could
check for that with
isnumloc =: *./@:e.&'0123456789'@>

(Note that it is an error for the first character of a numbered locale
to be '0').

this returns "boxed", which is technically correct, but it seems datatype lacks
the introspection to look beneath the box at the object.
So is there a way to get the type (i.e. class name if possible) of an object?
e.g. I have some variable Q (which happens to be an instance of MyClass).Is
there a way to create a verb, getTypeOf, such that getTypeOf Q
returns 'MyClass'
I couldn't find anything in JForC on this. At the moment I am finding it
difficult to differentiate boxedintegers from objects.
