Internal error with type() operator

[skyfex]

The following example results in internal error:

import typetraits

type Thing = ref object
    name: string

var x = new(Thing)
discard type(x.name)

Message:
test.nim(7, 15) Error: internal error: expr(nkTypeOfExpr); unknown node kind

It's not important to anything I'm doing, I just came across it when trying to create an artificial test case, so I expect it to be low priority.
