It's a bug. They either fixed it in a more recent version or it's a Windows
specific issue. On my Mac it works as expected:
$ ruby1.9 -v
ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-darwin9]
$ irb
arr = [1,2,3,4,5]
=> [1, 2, 3, 4, 5]
arr[0,2] = nil
=> nil
arr
=> [3, 4, 5]
Cheers,
Antonio

It's a behavior change in 1.9, use
arr[0,2] =
instead.

Here's what I get in Linux with TRUNK.
RUBY_DESCRIPTION

maybe macs are special? "Guess we're not cool enough" (from commercial).
Just kidding.
Take care.

Thanks, Matz.
It is exactly what I did.
I was not aware of the change ... or I forgot.
