hi
Reading a few introduction F# articles and presentations I made the
observation that the forward pipe operator is widely popular. Its also
a language feature that, when it comes up on blogposts or on
stackoverflow, its presented as a special F# feature.
In the Ocaml world the pipe doesn't have

ok, I had a similar attempt with
let tt x = function
a when x<=4 -> true
| _ -> false;;
but that gave me the following (scary -> 'a -> ) signature
val tt : int -> 'a -> bool =
so I stopped
thanks anyway

I try to transform an if-else clause into pattern matching, I think
I've tried a lot of approaches, but apperently I'm doing something
fundemently wrong.

I'm not actually new to OCaml, but although I've read every notable
book about OCaml and a lot of good code of other OCaml programs, OCaml
is still very foreign and counter-intuitive too me.

thanks Jake, after browsing through those articles I came to the
conclusion that for understanding and using camlp4 the notion of
quotations and antiquotations is fundamental. My absolute lack of
knowledge in this area might be a reason why I can't figure out how
camlp4 works.

thanks a lot for this information and the links, this is very helpful

hi
I'm a Ocaml n00b (without any degree). Therefore I have a faible for
everything that makes Ocamls syntax more algol/imperative like [1]. An
example would be an extension like 'newref'
(http://bitbucket.org/johannes/newref/wiki/Home), which turns:
print_int !i into print_int $i

Is there a web server interface / adapter for ocaml that abstracts
your application from the various web server implementations?
What is your prefered way to write a small web app for example a to-do list?

that's an interesting question, Here are a few thoughts:
technical:
- in .NET everything is easy (from the surface): you have your source
file (hello.cs) you take your compiler (cs.exe) and compile it to a
msil by
but that would be the big benefit of a clr like vm: It doesn't matter
how messed up, chaotic or just heterogen the environment is as long as
you can count on a regular execution of your portable bytecode.

ocamlc compiles to bytecode
ocamlrun interprets the bytecode
bytecode interpreter == vm
hence ocaml has a vm

my vision is a unix centric clr based vm:

- maybe a complete different base class library (like OcamIL)

- the vm is crossplattform, the bytecode is compatible
