Call operator fails to bind across imports

[Nycto]

Description

The callOperator fails to bind when the usage and declaration are spread across two different files. For example:

##
## myLib.nim
##
type
    Functor* = ref object
        callback: proc(): string

{.experimental: "callOperator".}
proc `()`*(comp: Functor): string = comp.callback()

and

##
## entry.nim
##
import myLib

type
    Bundle = object
        exec: Functor

proc someProc*(control: Bundle) =
    echo control.exec()

However, the same code does work when the import is removed:

type
    Functor* = ref object
        callback: proc(): string

{.experimental: "callOperator".}
proc `()`*(comp: Functor): string = comp.callback()

type
    Bundle = object
        exec: Functor

proc someProc*(control: Bundle) =
    echo control.exec()

Compiling with --experimental:callOperator instead works as intended

Ah, interesting. I suppose this bug report is really about error messaging, then. It would be helpful if the error expressed that adding the correct flags would fix the problem.
