Compiler optimisation notes when starting radiance

[Davidbhodge]

SBCL 1.3.20

For your information when loading radiance I get the following notes

They're just optimisation notes.

[Davidbhodge]

indeed - one might consider some declares?

(Micro) optimisation in general is not something I've paid much mind to yet, so I don't see much point in quieting these notes unless there's going to be a general optimisation-focused reworking.
