I think that this is definitely a wrong approach. The fact of the matter is
that when you get to complex record types, it is rather rare to use the
equality operator meaning just component equality. It seems quite unnecessary
to introduce the overhead resulting from gratuitous tagging just in case this
(mis)use occurs.
In practice I think that the problem is way overblown. Yes, it does cause
some troubles, as we see from yet another thread started up on the subject,
for those who don't know the language rules, but lots of things cause trouble
if you don't know what you are doing!
