Recent Haskell ignores the possibility of the automatic type
conversion. Thus,
1 + 1%2
is ill-typed.
Probably, this is because of the lack of a definite concept of which
value has to convert to which between the types.
On the other hand, my computer algebra project ha

Sure thing. A while ago I implemented several popular priority queue
structures. Being tired of proving them correct I worked out a simple
method of checking their correctness (or rather: the absence of errors)
at run-time. The idea is to cross-check a new i

You should look at Cardelli's paper on Service Combinators.
It contains a description of combinators to handle the unreliable aspects
of retrieving web pages.
I don't have a URL handy, but you should be able to find it with a quick
search.

This expression is perfectly well typed: Hugs 1.4 accepts it without
any problems:
