<mrvn> Think about that. A language where you have to be content with case insensitive output because its too hard to get the case right :)
<lus|wazze> [01:55:03] <lus|wazze> i dont think i can take malbolge seriously until i see a proof of its turing completeness
<lus|wazze> i can easily make a language in which it is even harder to write code than malbolge
<lus|wazze> that doesnt make it interesting
<mrvn> lus|wazze: Do you realy think anyone is ever going to proove it?
<mrvn> or disproove it?
<lus|wazze> obfuscated languages are only cool if they achieve turing completeness in cool and unusual ways
<lus|wazze> i dunno
<mrvn> Maybe Malborge is a language for wich you can neigther proove nor disproove that its turing complete. That would make it intresting.

<lus|wazze> ok if someone were to prove that its turing completeness is undecidable, THAT would make the language interesting
<lus|wazze> so far it seems just that nobody wanted to expend the effort necessary to disprove its TC
<mrvn> How would you? Prooving is normaly easy, you just build a turing maschine.
<lus|wazze> no idea
<lus|wazze> as im not a proponent of malbolge, though, i have not invested terribly much mental effort into the topic (i.e., none at all)
* Smerdyakov always drops safes on people who talk about joke programming languages.
<async> ocaml is naturally unobfuscated, sure, most all languages are
<async> but you can mess with people like this:
<async> type x = Begin | End | If | Then;
<async> if begin if begin End = Begin end then If else Then end = Then then begin End end else begin If end;

<mrvn> Thats a nice one.
<lus|wazze> well the best language for obfuscation, if you think about it this way, is definitely common lisp
<Smerdyakov> Maybe Haskell can catch up with Template Haskell.
<lus|wazze> with common lisp?? i doubt it
<lus|wazze> just think about set-macro-character alone ...
<lus|wazze> if you think about it, by defining a new syntax for set-macro-character which uses new macro characters, you could create a whole sub-language in lisp which is completely based upon rewriting its own lexical makeup
<lus|wazze> i dont think you could get more obfuscated than that
<mrvn> If set-macro is turing complete in itself you probably can#t top it.
<lus|wazze> defmacro most definitely IS - its just a representaiton of the lambda calculus
<lus|wazze> set-macro-character however does nothing else than define which function is called, when a certain character is encountered, to read the next input token

<emu> isn't the shorter way of saying that "is turing complete" ?

<Slackwarrior> hello!
<Slackwarrior> ppl i have a problem with let.... in syntax
<Riastradh> State your problem.
<Slackwarrior> i defined a recursive function and bound that uses that function under let
<Riastradh> Rephrase your problem.
<Slackwarrior> but the interpreter answers weird things...
<Slackwarrior> can i paste here the function?
<Riastradh> How many lines is it?
<Slackwarrior> 10
<Riastradh> Go ahead.
<Slackwarrior> let contract lambda t=let
<Slackwarrior> rec contractrec lambda t = match lambda with
<Slackwarrior> [] -> t
<Slackwarrior> | hd::tl -> let
<Slackwarrior> t'=singlecontraction hd t
<Slackwarrior> in
<Slackwarrior> if t'!=t then t' else contractrec tl t;
<Slackwarrior> t'=contractrec lambda t;
<Slackwarrior> in
<Slackwarrior> if t=t' then NoContract else ContractTo t';;
<Slackwarrior> weird
<Riastradh> I believe you need to create a new let expression to bind t' to the value of contractrec lambda t.
gt2 has quit ["Client Exiting"]
<Slackwarrior> under in?
<Riastradh> It should look more like this:
<Riastradh> let contract t =
<Riastradh> let rec contractrec lambda t = ...
<Riastradh> in
<Riastradh> let t' = contractrec lambda t in
<Riastradh> if t = t' then ...;;
<Slackwarrior> ah ok
<Slackwarrior> thanks
noss has quit ["[x]chat"]
<Slackwarrior> if i raise an exception in a function, will the function end?
<Slackwarrior> will the function stop at that point?
<Slackwarrior> helloooooooo?????
<Riastradh> Yes.
<Slackwarrior> ah ok
<Slackwarrior> thanks
