Update scene.mess: typo sequences: -> sequence:

[Shinmera]

What the org.shirakumo.trivial-extensible-sequences package is locally nicknamed to is up to you, and for trial's internal sources it is named sequences. This is not a bug.

Alright, thanks!

I didn't use any nicknames, just loaded the standard template from the getting started example https://shirakumo.github.io/trial/start.html

If your implementation provides a sequence package then that's what your implementation happens to do, not a universal standard.

I didn't know it is sbcl-specific, I looked it up, that is true. Thank you for explaining

[Shinmera]

I've added the nickname to the start guide as well to avoid confusion in the future.
