Find out whether and how the const qualifier should affect channels.

const chan is semantically the same as const * Channel, it's an immutable reference to a mutable channel.

Therefore var ref const chan const Object describes the following constraints:

this channel will return an immutable object const Object when reading from
the reference ref to this channel is considered immutable and cannot be swapped with another channel of the same type: ref = anotherChan // Compile-time error!
