Go 1.20 will include two new functions in theerrors package,Join andSplit.

golang/go@787f816

Two problems:

1. We usexerrors which most likelywill not be updated to support these new functions
   • The package is not only missing the new functions, it also has it's own implementations ofIs andAs which won't support the new functionality
2. Typingxerrors is unnatural for a Go developer and we often end up with a mix oferrors andxerrors

We usexerrors only because they include stack traces.

Proposal: We create our own in-projecterrors package (github.com/coder/coder/errors) where we wrap most of thestdliberrors functions except those where we want to extend the error with stack traces.

Ways to accomplish this:

• Forkxerrors and rename togithub.com/coder/errors (outside project), bring in line with stdlib
• Write our own stack handling, based onxerrors,pkg/errors or similar previous work.
