checking object type for a pragma is not possible

[RSDuck]

type
  User {.exportc, packed.} = object
    id: int

import macros

macro test(t: typedesc): untyped =
  echo t.getType()[1].symbol.getImpl.treerepr

test(User)

the output doesn't contain any informations of the pragma:

TypeDef
  Sym "User"
  Empty
  ObjectTy
    Empty
    Empty
    RecList
      IdentDefs
        Ident ident"id"
        Sym "int"
        Empty

Also the procs hasCustomPragma and getCustomPragmaVal don't support types. But the documentation contains an example of a custom pragma on a object(https://nim-lang.org/docs/manual.html#implementation-specific-pragmas-custom-annotations)

Also see here https://forum.nim-lang.org/t/3705

I found another problem:
Because of the implicit dereference hasCustomPragma and getCustomPragma don't work with ref types (https://github.com/nim-lang/Nim/blob/master/lib/core/macros.nim#L1224 where n[0] should be n[0][0] in case it's of the kind nnkHiddenDeref)
