Details:

It seems that the dispatching of overloaded functions is overridden by the
presence of files in the current directory, even when the current folder is a
class folder.

In the attached example, a class 'test' is defined. This class has a 'size'
function, to be used for objects of type 'test'. But when a method of the
'test' class calls the 'size' function on an object of a different type,
Octave tries to use this class method 'test.size' on this object of a
different type, instead of the standard 'double.size' function. This results
in an unexpected error.

Calling the following two commands illustrates the problem with text outputs:
  a = test
  func(a)

This behavior clearly differs from Matlab's, and creates code which is
location-specific: a function can produce a different result if it is moved
into a different folder.
