parser and modules seems broken

I try this

use StdIO: all;

noinline
Termfile::Termfile foo( Termfile::Termfile f)
{
    fprintf ( f, "hello\n");
    return f;
}

int main()
{
   TermFile::stdin = foo( TermFile::stdin);
   return 0;
}

on

-sbs-Bodos-IMac-> sac2c-d -V
sac2c 1.3.3-MijasCosta-778-gd0f9f
build-type: DEBUG
built-by: "sbs" at 2022-02-27T18:09:33

and I get

sac2c-d simple.sac
**  1: Loading SAC program ...
./simple.sac:4:11: error:
=> cannot load module `Termfile'!
./simple.sac:4:1: error:
=> type expected, `Termfile' found
./simple.sac:15:1: error:
=> function body or semicolon expected
abort: Failed to construct a syntax tree for `simple.sac'
compilation failed while Loading SAC program, 3 error(s).

I guess the problem is that StdIO already brings Termfile..... but that error message does not make any sense, does it?
