I don't think the point has been made clearly enough: the default `set` is a bitset. For _every possible value of the type_ , it stores a bit indicating whether it's present in the set. So you should use it only if the type has a limited range of possible values — usually with `enum` or `range`

ok. thanks.

I know that int alone is int64 cause int is defined to be as the size of a pointer and int64 is not allowed as written in the tutorial. So it seems i need to write the first number's type in the set explicitly to define the sets type.

`var s = {2.int16, 7, 8, 9, 10}` If you write just the literal digit its an `int` and not an `int16`. `int` is an alias for `int64`, on 64 Bit hardware.

var s: set[uint16] = {2u16, 7, 8, 9, 10} Run But the memory consumption is not what you want, instead use a hash set from `sets.nim`: import sets var s1 = toHashSet([9, 5, 1]) Run

Hello I'm trying to create a set using this line: var s: set[int16] = {2, 7, 8, 9, 10} Run and i get error saying: Error: type mismatch: got but expected 'set[uint16]' Run I tried to read the explanation in the tutorial but i can't get to
