/////// test.d ///////
import std.process;
import std.functional;

void main()
{
    pipe();
}
//////////////////////

The compiler is expected to either choose std.process.pipe, or present an
ambiguity error. Currently it chooses std.functional.pipe, with the resulting
error:

C:\...\std\functional.d(514,25): Error: tuple index 0 exceeds 0
C:\...\std\functional.d(514,42): Error: slice [1..0] is out of range of [0..0]
C:\...\std\functional.d(533,22): Error: template instance std.functional
.compose!() error instantiating
test.d(6,6):        instantiated from here: pipe!()
