Well, Ada requires certain errors to be detected at compile time,
so it is impossible to write a _pure_ interpreter for Ada -- something
like a Unix shell, which executes the first line before even looking
at the second line.  An Ada implementation has to look at the entire
program before running it.

But still, the part of Ada-Ed that runs the SETL structures or the bytes
or whatever, is an interpreter.  I claim Ada-Ed is a hybrid
implementation of Ada -- neither pure interpreter nor pure compiler.
