But 14 lines of glue for every different array type that I want to use
with Generic_Op?  That's the sort of repetition that turned me away
from Ada in the first place.  I like languages where I can say what I
want, and only have to say it once.  I don't like languages where I
have to cut and paste endless variations of boilerplate code.  For
that reason I like C++ and Perl and LISP and don't like Ada and Java
and C#.
