Looking at that code, I'm wondering how you pass a junction. Suppose I want to pass a junction to a subroutine instead of calling the sub with each value of the junction... how would I do that?

Tell the sub that it's expecting an undistributed junction as its argument:

Hrm. What happens if the junction is then used as an iterator?

$junction = File::Open("foo") | File::Open("bar);
for (<$junction>) {
...
}

Which could get interesting if inside the for loop the code creates more junctions and iterates over them. (Potentially ad infinitum)

And here I thought Quantum INTERCAL was a joke... :)
