The problem with undefined variables was fixed, but there is another bug related to scalar values. I assume N_Elements is determined as Product(Size(input, /DIMENSIONS)). However, a scalar value has a dimension size of 0, so the result of 0 elements.

function test_olSize::_OverloadSize
return, size(*self.value, /DIMENSIONS)
end

function test_olSize::Init, value
compile_opt strictarr
self.value = Ptr_New(value, /NO_COPY)
return, 1
end

pro test_olSize__define
class = {test_olSize, $
inherits IDL_Object, $
value: ptr_new()}
end

IDL> myObj = Obj_New('Test_olSize', 1)
IDL> Print, N_Elements(myObj)
0
