  Oops! I meant pointers as in "helpful hints", not the "pointer to
TYPE" sense. This is a section on common errors, and a few not so
common but really hard to find. 

  When trying to tell students to use loads of parens in macros defs I
liked the example as a case of something which appears to work but
fails because the parens are missing. Based on feedback from students,
a "horrible example" of what can happen if done wrong helps make the
warning stick.

  My use of 'Pointers" was certainly not clear in context.
