"method is not a base" on method with {.base.}

[Phytolizer]

I first raised this issue on nimlsp (PMunch/nimlsp#100) but was directed here.

The following snippet of code shows an error in nimlsp 0.3.2:

type
  UnimplementedDefect = object of Defect

  Node* = ref object of RootObj
  Statement* = ref object of Node
  Expression* = ref object of Node

  Program* = ref object of Node
    statements*: seq[Statement]

method tokenLiteral*(n: Node): string {.base.} =
  raise newException(UnimplementedDefect, "unimplemented: tokenLiteral")

method tokenLiteral*(p: Program): string =
  if p.statements.len > 0:
    return p.statements[0].tokenLiteral()
  else:
    return ""

It compiles just fine with Nim 1.7.1, but I get "method is not a base" within Emacs.

Flagging that I'm also seeing this, with Nim >2.1.1 in Emacs, using nimsuggest directly (rather than via LSP). The application compiles without errors or warning, but nimsuggest complains.

I'm also in Emacs (using LSP however), and I also get this message. Compilation succeeds silently for me too. Nim 2.0.2.
