It actually makes a lot of sense. For example, have you ever used
structures? The first element is at the address of the structure. Therefore
each item would be  Address + n - 1 (given that each element is 1 byte) this
would cause the first element to be Address + 0, the second to be Address +
1, etc..  This is a very crude example, but I think you get the point. Get a
copy of the old Win32Lib by David Cuny, and rip it apart, you'll see the way
he has structures set up. The new Win32Lib uses a more automated system for
stuctures so you never see any numbers.

The reason Euphoria uses 1-based indexing is to make it easier to read and
understand. In some languages you can even set the minimum base, like in
Visual Basic, with the command "Option Base 1" (i think, it's been a while
since I've used VB).
