Good advice.   When I want to use any term that might, however remotely 
possible, create any conflict, I add an "h" in some early location that usually 
won't change (much) the pronunciation or the meaning of the word.   If I would 
like to use "integer, " for instance, I use "ihnteger."  Just a personal 
attempt to keep myself out of trouble.
