Chan is an abstract type representing an unbounded FIFO channel.

Build and returns a new instance of Chan.

Write a value to a Chan.

Read the next value from the Chan.

Duplicate a Chan: the duplicate channel begins empty, but data written to either channel from then on will be available from both. Hence this creates a kind of broadcast channel, where data written by anyone is seen by everyone else.

Put a data item back onto a channel, where it will be the next item read.

Returns True if the supplied Chan is empty.

Return a lazy list representing the contents of the supplied Chan, much like System.IO.hGetContents.

Write an entire list of items to a Chan.

A weak channel writer. Sustained by the read head. Thus channel consumers keep channel producers alive.
