I agree it's not a big deal, but I still think it's something we might want
to change. Why introduce a mental speed bump if we don't have to?
Foo::new() returns a Foo, Bar::new() returns a Bar, Quux::new() returns a
Quux and a Channel::new() returns a... tuple of two items, neither of which
is a Channel (I know the two items together are conceptually a *channel*,
but they are not a Channel).

Using new() here seems like a usability loss for no benefit. But again,
it's not a huge issue (should still be fixed though).

Port & Chan are a bigger problem since users will forever have to
double-check which is which or will have to remember it.

Why the cognitive load? Channel::new_pipe() returning (Source, Sink) is a
usability win we get for free.

I know I don't have to convince anyone here just how critical good naming
