Try it out :) seems like a simple enough test program to write.

Values read from a channel will always be in the FIFO order, but that 
is not related to concurrent channel reads as those are, per se, not 
ordered in any way.


So can this result in one routine never getting any reads if there's a 
constant flow of incoming readers?

[go-nuts] Are receivers from a channel fifo?

[Tamás Gulácsi]

No. See what a select statement says about order when multiple cases are 
choosable: not defined, and the implementation guarantees uniform randomness

If I have multiple goroutines reading from a channel are they guaranteed 
to be FIFO i.e. is the handler that requested the read first guaranteed 
to get the first value, second to get the second and so on?
