What does 'shadows' mean?

[Francis Nugent Dixon]

Hi from beautiful Brittany,

Shadows is a bit of a misnomer, and is confusing.

I think the term "occult" would be better :>)

OCCULT

"Referring to the event in which one celestial body
passes in front of another, blocking it from view"

..... and I rather like the idea of global variables
being considered as "celestial bodies"

Tongue in cheek !
