Well, it is, but judging from my experience, comma operator is 
the most rarely used part of the language. I hardly ever needed 
it in C and C++, where it originated, same with D and Java. In 
fact, I had to check if it works in Java at all - turned out, 
it's only allowed in "for" loops. Just never used it and forgot 
about it.

The comma operator does more harm than good, is very rarely used 
and is far less usable than tuples, so I'm all for killing it 
(except in "for" loops).
