- Add support for reserve-job. Added in beanstalkd 1.12+

[scottmac]

Before 1.12, we'll return null if this isn't supported.

Fixes #221

[SamMousa]

Shouldn't we throw an exception? Returning null is not optimal for use cases where you reasonably expect it to return a value.

[scottmac]

I have no strong opinion on this, happy to change :)

[SamMousa]

Let me have a look tomorrow, will get back to you!

[scottmac]

Actually, I like that idea.

Also re-throwing an Unknown Command for older versions seems right

[SamMousa]

What happens if the response is not found?

Also there seem to be no tests included.

What's happening with this? I've forked the repository specifically to merge in and use this feature. I'd rather move back to yours, though.

[SamMousa]

Apologies, shifting priorities, I'll try to plan some time for this soon

[seth-xdam]

Cool. If it helps, we've been using it in production without making any changes besides what's already in this PR. Thanks for your work!

[SamMousa]

I'm merging this, but it will only be available in the next major version of this library, just an FYI.
That version will very likely require PHP8.
