[ruby-core:69507] [Ruby trunk - Feature #11007] Prime.each.with_index should accept offset

Issue #11007 has been updated by T Yamada.


Hi, any progress about this patch?

The reason why I have proposed this is that I'm anxious about the phrase of http://ruby-doc.org/stdlib-2.2.2/libdoc/prime/rdoc/Prime.html#class-Prime-label-Generators : "Furthermore, it is an external iterator of prime enumeration which is compatible with an Enumerator."
"Compatible Enumerator" should accept with_index(offset)...

----------------------------------------
I'd like to execute following code:

~~~
Prime.each(10).with_index(1){|e,i|
  print i,' ',e,"\n"
}
~~~

Expected output:

~~~
1 2
2 3
3 5
4 7
~~~

I have attached a patch.
