Hello,
Currently I'm using a reference class in my script to manage data
exporting.  Sometimes, when I run my script things will be progressing as
expected when (seemingly mysteriously) every method in the object will
return "Error: attempt to apply non-function".  Attempting to recreate the
object will then result in a "non function" error message about the
initialize function, which I've also defined in the class definition.
Re-sourcing the file containing the reference class definition will then
fix the problem, i.e. all methods will work as expected.  Has experienced a
similar problem?  It doesn't appear to be caused with actual errors
produced by my script, so I'm not certain where to start looking.  Any
ideas?  Thanks for your time.
