I agree that this is wrong. In OO terms, it exposes the impementation to
the user. It's wrong for templates, but it's also wrong for ordinary
classes. If I decide that I want to change some part of the interface
from being a plain integer to calling a method, why should the users of
the class care.
Languages such as Eiffel have got this right, and yes Greg, Perl 6 will
too :-)
