In Preferences>>class there is:

compileAccessMethodForPreference: aPreference
	"Compile an accessor method for the given preference"

	self class compileSilently: (aPreference name, '
	^ self valueOfFlag: #', aPreference name, ' ifAbsent: [',  
aPreference defaultValue storeString, ']') classified: 'standard  
queries'


This will result in methods with a trailer of #(0 0 0 0)...
