Re: Docs: Clarify that accessing field beyond the last one throws lint warning.

[arnold]

Hello.

Thanks for the note. I suppose I can add a note about this, as there
are other places in the manual that make note of lint warnings.

However, as there are close to 200 lint warnings in the code, it
doesn't make sense to document them all.

Thanks,

Arnold
