[Keith Wansbrough]

I forgot to mention:

With regard to the dangerous practice of using "==" (as in your `elem` 
example) on Double, every computer scientist or programmer should read 
the following paper at some point in their training:


David Goldberg, "What every computer scientist should know about 
floating-point arithmetic". ACM Computing Survey Volume 23 ,  Issue 1  
(March 1991) Pages: 5 - 48.
