Here's my point. The '65 Mustang is cool and all that,
but you don't have to file the points and clean the carburetor
on the new model to get good performance. It just happens.

Why all the tricks? Why not just use a modern programming
language and be done with it? What is it about IDL that
keeps you so preoccupied with modifying it in all these
different ways?

Surely there is something better than IDL that meets your
needs. Or, isn't there?

I'm not trying to be antagonistic. I'm just curious.

Cheers,

David
