Julia feature request: Alternative

[eschnett]

See JuliaLang/julia#17073 -- this feature request is very similar to what you implemented.

[kmsquire]

The request here seems to be only abstractly related to Result types (as I understand them), and the corresponding Julia issue was closed (with a PR that implements essentially what was requested).

So this can probably be closed. If something like this is still needed, it should probably live somewhere else (base Julia or a separate package).

Result could possibly be implemented using a hypothetical implementation of this, but the compiler is good enough now that the current Result type is probably good enough.

@0x0f0f0f Maybe this can be closed? @kmsquire summarized it well a while ago.
