I guess you are correct. I did not notice that these
were unnecessary.

Thanks also for fixing the spelling of Fahrenheit... 
it is misspelled as often as Gandhi.  ;)

The block semantics for Hash -- when was this
introduced? I recall it was discussed long before it
was implemented. 

I commonly use 1.6.5, and it is 
not there. Is it in any 1.6.x, or is it a 1.7ism?
