A Minor Addition to IDL Syntax [message #9397]

Hi,

Often I need to make variable length lists in IDL. To do this I like to
use the concatenate syntax. For example to put array y on the end of x I
use:

x=[x,y]

The problem with this is it fails if x is not defined. I think it would be
nice if when x is undefined then x=[x,y] automatically becomes x=y.
Can anyone think of a reason for not modifying IDL to allow this? Or is
there a better way to make lists?
