Passing $ to a typed param of a macro yields a single nnkSym instead of a nnkClosedSymChoice

[liquidev]

Because $ is overloaded, I would expect an nnkClosedSymChoice to be returned.

Example

import macros

macro dumpRepr(x: typed): untyped =
  result = newLit(x.treeRepr & "\n")
echo dumpRepr(`$`)

Current Output

Sym "$"

Expected Output

ClosedSymChoice
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"
  Sym "$"

Additional Information

• dumpRepr(typeof `$`) works, but wraps the node in an nnkTypeOfExpr
• This issue is a problem for euwren, since you can't wrap stringifying procs without using a wrapper proc
