What should "(1..3).chunk" (i.e. without a block) do?

It issued an
ArgumentError: tried to create Proc object without a block

I changed the error message to "no block given" which I hope to be more informative, but maybe there is something more useful to do here?

A default block of {|x| x} doesn't seem all that useful.

Returning an enumerator that, upon completion, will return an enumerator would probably be better, but could also be a bit confusing if someone doesn't realize he forgot to specify the block?

Thanks to Run Paint for raising the question when writing the rubyspec for #chunk.
