yes; but it still is other way around; so one has to take one more step.

irb(main):016:0> x="string"[0]
=> 115

irb(main):021:0> x.chr
=> "s"

# or

irb(main):022:0> x="string"[0].chr
=> "s"



i was hoping to get

irb(main):016:0> x="string"[0]
=> "s"

thinking that a string is a sequence of chars. i do not want to think char
as int (or long :); it feels like asm/hardcoreC prgg...

it is really a nuby thingy question. may not be important really...

thanks and kind regards -botp

irb(main):001:0> "string"[0, 1]
=> "s"

I believe it's planned to have "string"[0] return "s" in Ruby 2, as
well.
