<ulfdoz> ocamlyacc gives me the message "9 rules never reduced". Reduced to what? Good or bad sign? I do not really know how to interprete.

<mflux> it's been some time since my compiler course, but maybe it simply means they're not referred to, that is, they are never used?
<mflux> or are they?-)
<ulfdoz> At least they should all be necessary.
<ulfdoz> But your hint helped. I forgot to include the productions for some control structures which would result in what you mean.

<ulfdoz> Probably a stupid beginner question, but anyway: Where is the difference between a type "('a, 'b) t" and a type "t of 'a * 'b"?
<mellum> ulfdoz: the latter is not a type.
<mellum> rather, it's a syntax error.
<Demitar> The more useful explaination is that "T of foo_type" is a variant with the a value of type foo_type attached.
<Demitar> :)

<Demitar> Any recommendations on what to use to pack bits into a string? (Need to encode packets manually for a network protocol.)
<Demitar> (I'd like something like the python struct module.)

<quamaretto> If you're using a Mutex inside a function and you need to return a value from between the locking and unlocking, is there a more graceful way to do it than using a mutable type?
<Submarine> ah I stupid or can you just use a let ... = .. in ?
<quamaretto> How would I use that?
<Submarine> lock ; let return_value = computation () in unlock; return_value
<Submarine> you may want to wrap the computation in a try clause
<quamaretto> Ah
mrsolo has joined #ocaml
<Submarine> lock ; try let return_value = computation () in unlock; return_value with exn -> unlock; raise exn
<quamaretto> That's what I was trying to think of, thanks
