To some extent I agree, but I also think that generic functions are
even more flexible. (As per the previous discussion which started
covering adaptation and moved on to generic functions).

I'd like to see some clear evaluation of the pros and cons of the 3 -
interfaces, adaptation, and generic functions. My feeling is that they
are to some extent "competing" proposals, and we need agreement (or
BDFL ruling!) on which is the way forward, before we start discussing
specifics.
