[ruby-core:45167] [ruby-trunk - Feature #6445][Assigned] request for default length/position on string index

From: "mame (Yusuke Endoh)" <mame@...>
Date: 2012-05-21 11:59:49 UTC
List: ruby-core #45167
Issue #6445 has been updated by mame (Yusuke Endoh).

Status changed from Open to Assigned
Assignee set to matz (Yukihiro Matsumoto)

Hello,

I created a patch that add a syntactic sugar from (arg..) to (arg..-1).

  ary = [1, 2, 3, 4]
  p ary[2..]  #=> [3, 4]

Matz, what do you think?

Feature #6445: request for default length/position on string index

would be nice if ruby has default for "rest or up to end of string"

eg

"hello"[2,] =>	should default to "hello"[2..-1]
or 
"hello"[2..] => should default to "hello"[2..-1]
