Prefix names used as arguments

[soegaard]

The following program:

#lang rhombus
import:
  "racket-port.rkt":   prefix port

fun read(port): port.to_string(port)

results in the error

to_string: no such field
  in value: #{'#<input-port:/Users/soegaard/Dropbox/GitHub/rhombus-experiments/big.txt>}

This makes sense, since in port.to_string port is now bound to the input argument.
The intention was however to use to_string which was imported from "racket-port.rkt".

Is there a way to get the to_string imported from "racket-port.rkt" if the identifier port is shadowed?

The file racket-port.rkt.

#lang racket/base
(require racket/port)
(provide
 (rename-out [port->string to_string]))

In many languages, there is a way to refer to the global or top-level namespace. For example, in C++ you would write a leading :: before an identifier. It's not clear to me how to do this in Rhombus.

Along those lines, my first thoughts were something like:

fun read(port): .port.to_string(port)        // or
fun read(port): ().port.to_string(port)      // or
fun read(port): _.port.to_string(port)

Maybe there is a better way to do it.
