10:15 anonymou1: Hello everyone!
10:15 anonymou1: Tell me, please
10:16 anonymou1: Is it bad style to write (define (a) 2) instead of (define a 2) if I want to?
10:16 anonymou1: so - use function instead of a simple variable
10:17 bremner: anonymou1: if you know why you want to, I guess it's OK. Why do you want to?
10:18 anonymou1: bremner: just because I like it this way. I may seem crazy(tell me, please if so).
10:18 lewis1711: LOL. fair enough
10:19 anonymou1: Maybe I see variables as strange in case of lisp as strange as...
10:19 bremner: anonymou1: you will probably confuse other people reading your code.
10:19 lewis1711: why are variables strange in lisp?
10:19 anonymou1: just as strange as making a new type of data as printing
10:19 anonymou1: i.e.:
10:20 anonymou1: (define |print-line "Hello, World")
10:20 anonymou1: )
10:20 bremner: I don't get it.
10:21 bremner: that just gives a name to a string
10:22 anonymou1: bremner:  a minute, I am going to try to say it better
10:22 bremner: anonymou1: if you want to define non-trivial functions, you need to use parameters, which are like variables.
10:25 anonymou1: in case of lisp, as I see, adding variables when we have functions a bit more complicated when it is don't needed(I want to pay your attention: I have no much experience with programming). What is variable? For me it seems pretty enough to say: "a function that doesn't do anything else instead of returning a value"(today we have syntactic difference, I mean lisp could change and be more minimalistic).
10:25 (quit) mizu_no_oto: Quit: Computer has gone to sleep.
10:26 bremner: anonymou1: well, how would you like the syntax for (define (add1 x) (+ x 1)) to be?
10:26 bremner: anonymou1: mutation is another issue, which in principle you could avoid. e.g. (set! x 1)
10:27 anonymou1: i don't want to treat functions that only return a value as something Special. Just as I don't want to treat functions that only print some text as something Special. I want your syntax to be (define (add x) (+ (x) 1))
10:27 anonymou1: the*
10:27 asumu: anonymou1: note that functions are not "special". (define (a) 2) just means (define a (lambda () 2))
10:27 anonymou1: the syntax
10:27 asumu: (so if you find variables strange, function definitions should be strange too)
10:28 lewis1711: yeah define sort of does two things.

10:44 anonymou1: so I am a bit afk, thank you very much for the answers.
10:44 bremner: anonymou1: I think you're correct there is asymmetry, but the asymmetry is in using a different syntax to call a function than to evaluate a variable.  E.g. Haskell takes a different approach; afaik there is no syntactic distinction between variables and zero argument functions there. It's just a different set of design tradeoffs.
10:44 bremner: sure, take your time ;).

11:22 lewis1711: not exactly, but programming and maths share many concepts

11:23 bremner: anonymou1: I think one thing you are missing is that there is no "address of function", there is just lambda's (or procedures values)

12:13 asumu: There is `remp` from R6RS

12:13 mithos28: it takes a third arg
12:14 asumu: That's an equality predicate, but not an arbitrary predicate.
