Hi list,
Does someone know how to write a camlp4 quotation for types of the form 'a *
'b * 'c * 'd ... For now I could only obtain types of the form 'a * ('b *
('c * ('d * ... )...))), using a code similar to
List.fold_right
(fun x accu - :ctyp $x$ * $accu$ )
(List.tl tuple_types)

Self-answer, though I'm not sure that's the prettiest way (not even sure it
is even valid) :

Dear list,
I'm am very happy to announce the first release of naclgrid, a light desktop
grid engine written in jocaml and relying ocsigen.
Basically, it's a server where

After installing ocaml on windows, I've be shocked by the old fashioned icon
that appears on the desktop. To say it frankly, compared to the other icons
showing up on the desktop, it seems quite ugly.
Is there somewhere any good replacement for it ?
Well, this was an incentive to learn inkscape and draw my own icon...
Here is what I could come up with:

This is based on the icon I found at

What do you think ;) ?

Why do the first two programs type-check but the thrid one does not?
let f x = x in (f true, f 3);;
let f (x : 'a) : 'a = x in (f true);;
let f (x : 'a) : 'a = x in (f true, f 3);;

Err, good question. :-)
# let f : _ = fun x - x in f true, f 3;;
- : bool * int = (true, 3)
# let f : 'a = fun x - x in f true, f 3;;
Error: This expression has type int but is here used with type

The type of f here is
Is there something that can complete this analogy:
(=) is to (==) as Pervasives.compare is to ___?
That is, is there a polymorphic total ordering with respect to *physical*
entities, rather than to their structure?
I'm afraid of getting into trouble with Obj.magic, but what would this do:
let f

No, but it'd be pretty trivial to implement through

I'm guessing the scope of the 'a is not what you'd expect but I have
no idea
why. I'd have thought the latter would be a harmless type annotation...
My guess is that the problem here is not about scope but
14 matches
