3395 :: Table: proc `[]`is deprecated, but "get" is not "public" !?

  Hi.

  I'm trying to clone the "table" code to run (unguarded) on the shared heap, and I noticed something strange; in the tables module, there are procs like this:

  proc `[]`*[A, B](t: Table[A, B], key: A): B {.deprecatedGet.}
  Run

  So we should not use table[key] anymore, but table.get(key) instead. That is why I deleted those [] procs at first. But then, OTOH, the "get" template is not marked with a "*", so you cannot use it instead of "[]" anyway!

  Does that mean that "[]" is not deprecated after all?

  import tables
  
  proc testAll(): void =
    var t = newTable[int,int]()
    t[1] = 2
    echo($t.get(1))
  
  testAll()
  Run

  when defined(nimTableGet):
    {.pragma: deprecatedGet, deprecated.}
  else:
    {.pragma: deprecatedGet.} # active branch: a nop
  Run

  It's not deprecated. The nimTableGet define was introduced in order to help people migrate Nim code from some version where [] returned default(T) to some other version where [] began to raise an exception.
