The method category 'system primitives' in class Symbol include 3 methods
(#isKeyword #isInfix #isPvtSelector) which should belong in a 'testing'
category, along with the obviously missing #isUnary ala:

isUnary
     "if I'm not infix(binary) or keyword"
     ^self isInfix not and:[self isKeyword not]
