Unable to have array of NimNodes declared with const

[PMunch]

While trying to create a mapping table from strings to internal types for use in a macro I noticed I got weird errors when trying to have NimNodes in a const array:

static:
  let testArr = [parseExpr("int"), parseExpr("float")]
  const testArr2 = [parseExpr("int"), parseExpr("float")]

  echo testArr[0]
  echo testArr2[0]

This creates an error "Error: cannot generate VM code for int" for the second echo statement. Removing the echo statement makes it work fine, even with the declaration of the const. The let works fine.

Maybe it doesn't make sense to make a compile-time const?

Well doing it like this:

const test2 = [parseExpr("int"), parseExpr("float")]
static:
  echo treeRepr(test2[0])

or like this

const test2 = [parseExpr("int"), parseExpr("float")]
echo treeRepr(test2[0])

crashes the compiler with the error

lib/core/macros.nim(377, 1) Error: internal error: expr(nkIdent); unknown node kind
No stack traceback available
To create a stacktrace, rerun compilation with ./koch temp c <file>

well, just use let inside the static block. It is static, it will not be there at runtime

Yeah I know how to work around it, but at the very least this should throw an better error. Or in the case of the compiler crashes an actual error instead.
