avoid fatalError

[xlc]

It will be good if the API can be improved to avoid fatalError. e.g. throw or return false on trying to send on a closed channel.

Perhaps we can introduce a sendOrThrow function that throws when the channel is closed? Such a function could optionally be used in place of send. Would this work for you?

This library is heavily modeled after go and one of those design choices is not allowing a send on closed channel. However we can support both by making a more explicit function for this behavior.

that will work. maybe we can call it trySend but that could have other means (e.g. only send when buffer is not full)

[gh123man]

I had considered trySend however I feel that it would read weird when written like:

do { 
    try trySend()
} catch ...

Ill put some more thought into it.
