Perhaps this time you should invoke the principle of least confusion... 
(although I can see the argument both ways)

If you allowed passing a block to .new, then it would be meaningless to 
return a file object, so your choices would be either nil or the block 
value. If you made it the block value, then folks wouldn't have to 
remember the difference between open and new.

There are many other methods whose return value varies if a block is 
given, so there are precedents.
