   In general I like the idea of writing code in a way that does   
   not require the reader to have memorized ten thousand things from   
   the language spec.   
      
   But I do not consider this a matter of remembering the specific   
   details about an operator - I consider this a matter of remembering   
   what operator a symbol represent.   
      
   I consider "short circuiting AND" and "non short circuiting AND"   
   to be two different operators.   
      
   And in C then && is the first operator not the second operator.   
      
   And understanding what operator each symbol represent is not   
   detail but core. IMHO.
