Hi Oscar,
see Object class>>whatIsAPrimitive. Further, most of the primitive
methods you're seeing are methods that answer self, nil, true false or an
inst var. See the difference between these:
SystemNavigation new browseAllSelect: [:m| m isQuick]
SystemNavigation new browseAllSelect: [:m| m primitive > 0 and: [m isQuick
not]]
SystemNavigation new browseAllSelect: [:m| m primitive > 0 and: [m isQuick
not and: [(#(117 120) includes: m primitive) not]]]
