Runtime variable name definition. The history repeats itself for sure.
I was told by RSI developers when I started in IDL that once you find
yourself wanting this, it means that your progamming needs serious
phylosophy readjustment.
One side effect is that any time you save and restore a runtime-named
variable you need to again find out what the name of it is. And it is
not the only flaw.
I came to IDL from IGOR Pro, where meaningful names are the cornerstone
of it all and programming holds together by explicit naming conventions.
But in IGOR it is so because you have all your variables at the global
(*main*) level. IDL allows a lot more flexible approach because it is a
*reuseable* development environment.

Cheers,
Pavel
