Sadly, 50000! (Process is terminated due to StackOverflowException.) is lost to the ages because someone decided to use the stack for bignums.

Let's discuss F#

It's a watered-down SML (without even functors!) with a joke of a C# interop as an added humiliation [/thread]

Haskal with exceptions

isn't it just a NIH version of ocaml?

>>4
Worse. OCaml had functors, F# lost them.

>>4
I've used ImageJ, but never knew they had a version of OCaml, link please.

I can confirm that F# is a turd.

Why don't you geniuses write some patches then? Isn't it all OSS now?

No matter how much you hate Microsoft, the fact remains that F# can be used to force some functional programming into corporate enviornments with minimal executive friction

You might even enlighten some C# tards with your a(u/r)tistic functional implementations of boring business logic

>>8

Isn't it all OSS now?

No. It's all ALSA and PulseAudio now.

>>8
It needs to not be shit first.

>>1
Thanks for the chuckle.

open System.Numerics
let rec fact (n: BigInteger) = if n < BigInteger 1 then BigInteger 1 else n * fact (n - BigInteger 1)

System.Console.WriteLine("{0}", fact (BigInteger 5000))

I still don't get the rules for F#IOC. Does it not work right in the piece of shit they call a repl? At least open and module work, so there's no excuse for the trash posted in >>1

So this program works fine for me even though it's not tail-recursive. I'm still using an old mono that doesn't have the improvements from the MS source yet.

It's a shame about functors. I could get around the REPL but I mean what do people do without functors? Isn't that the #1 reason anyone bothers with OCaml?

>>9
USE="alsa jack -pulseaudio -systemd -lennartpoettering -sjw -feminism -marxism -jews ..."

>>11

I still don't get the rules for F#IOC.

The indentation level determines whether a line of code belongs to the one above it or is a new statement. For example, add a space before System.Console.WriteLine("{0}", fact (BigInteger 5000)) and you get
error FS0010: Unexpected identifier in binding. Expected incomplete structured construct at or before this point or other token.
error FS3118: Incomplete value or function definition. If this is in an expression, the body of the expression must be indented to the same column as the 'let' keyword.
error FS0010: Incomplete structured construct at or before this point in implementation file
Still better than Sepples' error message though (but I haven't tried any metaprogramming in it).

At least open and module work, so there's no excuse for the trash posted in >>1

I take offense! It is sacred /prog/ heritage to set things you don't like up as a strawman and make them look as bad as possible to strengthen your own position in comparison. Do you think I was typing System.Numerics.BigInteger over and over again? Of course not. I added the excess in just before making the post. _{^{(Actually, I first did it with Complex, butI wanted a large integer output too.)}}

So this program works fine for me even though it's not tail-recursive. I'm still using an old mono that doesn't have the improvements from the MS source yet.

It isn't in the latest .NET framework either, apparently. Whatever got installed with VS2013 and is the build target by default.

>>12
Whoa, fellow Gentoo user in this place?

>>14
While I imagine you'll see certain personalities^* feigning preference for Plan9 or Symbolics' Open Genera LISP operating environment, in practice most are probably are just using Linux Mint, Debian, Arch, Gentoo, FreeBSD, OpenBSD. Or perhaps even Windows because they don't actually program anything and just like to post about how Rust is so hip and cool and progressive and radical and if you don't use it you're a racist, White supremacist bigot.
