Sorry, I misread again: you want _your_ own OPEN function. In this case why
don't you shadow OPEN in your application and force it to return gray
streams? All packages in your application will see the shadowed symbol.
The other alternative, redefining OPEN, only works if you tell the compiler
not to inline OPEN with a global (proclaim '(notinline open)), for
otherwise it will use the C function in the generated code.
