Hi,

I created two functions that improve the syntax of declaring a map.

let (=>) x y = x,y

let map x = Map<_,_> x

// Because of this we can write

let foo = map[1 => 1; 2 => 4]

enjoy!![;)]

What`s wrong with this declaration?

let foo = Map [1, 1; 2, 4]

First of all that won't work you have to write:

let foo = Map<_,_> [1, 1; 2, 2]

Also writing it the way i showed is better because you map keys explicitly to values instead just putting a tuple which can be confusing.

Great! I like it. I also find it more readable (but I don't see the need for your map function):

let foo = Map [0, 1; 1, 2; 2, 4; 3, 8; 4, 16]

 

let pot = Map [ 0 => 1
                1 => 2
                2 => 4
                3 => 8
                4 => 16 ]

Notice that you can omit the semicolons in the second form. Plus, I find it more consistent with how Visual Studio displays it:
