Craig has hit the nail on the head with many of his suggestions.
There are many changes that could be made to IDL that would be convenient to
some but inconvenient to others. The best changes, however, would be those
that improve IDLs useability to everyone (no matter how small the
improvement).

In particular:

I think changing these 3 small details would add alot of elegance to IDL, and
would benefit everyone.
