10902 :: how to define a zero capacity HashSet with let ?

  we can define a zero cap HashSet by var

  var a: HashSet[string]
  Run

  but how to do same thing by let?

  This works:

  import std/sets
  let a = initHashSet[int](0)
  Run

  But why would you do that? With let you won't be able to mutate it, so it's effectively useless.

  Seems it can work

  let a = HashSet[string]()
  Run
