Did you consider parameterized packages? The idea is you can declare a set of related objects/types/methods as well as have concrete type specific initialization. E.g.

  package stack[t]
  type Type []t
  func New() Type { return Type{} }
  ...
  

Then it can be used so:

  import s “stack”[int]
  var s1 = s.New()
