comment Method for variable substitution in multiple summation
@Will Jagy: Thanks for suggestion. I've posted it there. @Gerhard Paseman: Great! I read the Chapt.2 and found the interesting Iverson's convention, which led me to the wikipedia page for "Iverson bracket" and Knuth's note on arxiv (arxiv.org/abs/math/9205211).
