Subject: [ruby-talk:01786] Is this a bug?

(mailed & posted)

Hi,

I am using Ruby 1.4.3 yet! Now I have found a behavior that seems not
in-line with the documentation.

Please consider:

   /home/hintze/$ ruby
   $_ = "hello"
   p "1st: #$_"
   sub("e","a")
   p "2nd: #$_"
   ^D
   "1st: hello"
   "2nd: hallo"

It seems, that Kernel::sub also updates variable $_. From the
documentation I would assume, that it should only return a copy, and
shoud *not* update $_.

Updating $_ should be the task of Kernel::sub!.

Am I wrong?

\cle

PS: Same is for Kernel::gsub.
