C > Haskell

Name: Anonymous 2015-10-17 14:21

C can do arrays and trees. Haskell can do trees but cannot do arrays. C is the winner.

Name: Anonymous 2015-10-17 14:24

Arrays are specified in the Haskell2010 standard.
See <https://www.haskell.org/onlinereport/haskell2010/haskellch14.html>

Immutable arrays are a joke.

Python has to do indentation but can avoid parentheses. Lisp has to do indentation too but cannot avoid parentheses. Python is the winner.

Those are based on C FFI. They are C arrays, because Haskell cannot do arrays.

but can C do monads?

Obviously. Even the Haskellists admit it.

Haskell is just a C program.
You can do everything Haskell does (and much more) using C.

C can do manual memory management and GC. Haskell can do only GC. C is winner.

lisp doesnt't require indentation though mega retard

It does in practice. Look at any real Lisp code and it's indented like Python because otherwise it would be unreadable. Parentheses only help the computer, the human needs the indentation.

You probably have never seen real Lisp. Have a look here, it's all Python with extra parentheses:

Every language has its indentation conventions. That doesn't mean FOIC.

Try to write Lisp without Python-style indentation for a day. You'll howl.
Besides, admitting that Lisp has an indentation convention is already a failure on your part, because that means the parentheses should be optional not mandatory.

emacs can automatically indent your lisp for you.

But can it eliminate unnecessary parentheses?

Yes, but that feature is only supported by the ocamlc Lisp compiler.

How would you propose writing an expression like (+ 1 2 3 (* 4 5 6) 7 8 9) without parens?

+ 1 2 3 * 4 5 6 7 8 9 does not work

+ 1
2
3
* 4
5
6
7
8
9
works but cannot be on one line.

+ 1 2 3 * 4
5
6
7 8 9 just looks extraordinarily strange to me, and would get worse with more complicated expressions.

In Lisp, you could write the expression with the original spacing, or like this:
(+ 1
2
3
(* 4
5
6)
7
8
9)

or like this:
(+ 1 2 3 (* 4
5
6)
7 8 9)

and it is simple to write an interpreter -- the spacing does not matter. Writing an interpreter to work without parens would be much more complicated and error prone. The parens allow the programmer to choose whatever indentation style makes the most sense for the application.

As an after-thought, how could you maintain the first-class citizenship of functions without parens? How would you know whether a function name is being passed as a parameter or if it is being called? With parens it is simple -- see if there is an open paren directly before the function name.

I inline Lisp all the time. No indentation, or any other special characters (like Python's semicolon bullshit) required. Plus, I can put a lambda on one line or as many lines as I like, unlike FOIC.

Also, Python simply cannot do a multi-line lambda, purely because of FIOC. I know I already mentioned that, but it's an important enough example to bring it up again.

Why wouldn't you want all strings to be represented as lists? It's not that much overhead, and the performance loss of having to traverse a list that will never change or be reordered isn't that important.

Erlang stores strings as lists of integers. But it is not a Lisp, and can go fuck itself up its own monitor port.

As always, the Lisp excuse is "we're shitty programmers and cannot solve any complicated problem waahaaa".

The parens allow the programmer to choose whatever indentation style
But they don't allow him to choose a style without parentheses in case he indents following a certain convention which is what most Lispers do.

>>20
If it's first on the line or follows a parenthesis, it's called. Otherwise, it's passed. You should really learn Haskell syntax.
