3141 :: expandMacros macro bug?

  Hi there,

  Quick question coming from a newbie to Nim (Love the language btw :) ) The question is in regards to the expandMacros macro in the macros module. Here is the most basic macro that I can find that demonstrates the problem:

  macro named(identifier): untyped =
    result = newProc(identifier, [ident("string")],
      newNimNode(nnkWhileStmt).add(
        ident("true"),
        newNimNode(nnkReturnStmt).add(newStrLitNode("hi"))
      )
    )
  Run

  just doing

  named(TestMethod)
  Run

  Doesn't raise any problems however doing

  expandMacros:
    named(TestMethod2)
  Run

  Does raise some problems with the compiler: https://ibb.co/dcZN6v

  From my very limited knowledge is seems the problem comes from the expandMacros injecting some weird gunk into the expansion. Although I could just be completely blind/wrong to something.

  Anyone got any ideas?

  Thanks,

  -Andy M
