runtime: zip

[avelino]

(zip (list 1 2 3) (list 4 5 6) (list 7 8 9)) ;;=> ((1 4 7) (2 5 8) (3 6 9))
(zip (list 1 2 3) (list 4 5 6))              ;;=> ((1 4) (2 5) (3 6))

[trumae]

In the lisp way the right is:
(zip '(1 2 3) '(4 5 6) '(7 8 9)) ;;=> ((1 4 7) (2 5 8) (3 6 9))
(zip '(1 2 3) '(4 5 6)) ;;=> ((1 4) (2 5) (3 6))

Or can be like Clojure:
(zip [1 2 3] [4 5 6] [7 8 9]) ;;=> [[1 4 7] [2 5 8] [3 6 9]]
(zip [1 2 3] [4 5 6]) ;;=> [[1 4] [2 5] [3 6]]

That is needed for the language decide when evaluate a parameter as a function call or as an simple data list. In your example: (1 2 3) is an list or the funcion "1" applied on parameters 2 and 3? And how does works an form like (get-data "sample 1" 300) used as an zip function parameter?

[trumae]

Another solution is always use an function as list constructor when an list is needed. Like:
(zip (list 1 2 3) (list 4 5 6) (list 7 8 9)) ;;=> ((1 4 7) (2 5 8) (3 6 9))
(zip (list 1 2 3) (list 4 5 6)) ;;=> ((1 4) (2 5) (3 6))

The "list" word/function can be replaced by "array".

[crgimenes]

About lists, if the first element is not a function or lambda we can assume that it is just a list.
Example:
((1 4 7) (2 5 8) (3 6 9)) it is a list of lists.
(print "test") it is a function with a parameter
(array (print "test")) or (list (print "test")) it is a list, function print is te element 0 anda the string "test" is the element 1
'(print "test") is the same as the previous... although I do not like this version
() and finally this is an empty list, if used in an if or for is the same as false.
I believe that in this way we leave the use of lists very simple and intuitive.

[trumae]

So it will be impossible to declare one list of functions or lambdas?

[avelino]

We will follow the same run of Go, array serves for both approach (Array and list)

[crgimenes]

@trumae I do not know if I understood correctly, but to declare an array of functions just put the word "array" at the beginning.

[trumae]

That solution is good. But the (zip (array 1 2) (array 3 4)) is different of avelino's examples. My problem is with the solution using inference to decide between data list or function call. Regards, Vinicius 2018-02-13 23:20 GMT-02:00 Cesar Gimenes <notifications@github.com>:
