Well, my question is this. If I can do something like:

#(set-global-staff-size 18)

\paper {
 #(define fonts (make-pango-font-tree ... (/ staff-height pt 20)))
}

where staff-height gets referenced _outside_ of the 
set-global-staff-size call, then why can't we just reference it 
directly within the make-pango-font-tree syntax? It appears that the 
variable/property is stored somewhere, but where? and why can I 
reference it, but make-pango-font-tree can't?
