There's no send! in 1.9. I wish there were; I like send/send! more
than public_send/send, and I think Matz put it in there briefly but
then decided that switching the sense of send was too
backwards-incompatible. Also there was some question which was the
"dangerous" one: the one that included private methods, or the one
that didn't.
It appears to be gone from Rails, so maybe it was only there during
the brief period that it was in 1.9.
$ ./script/console
Loading development environment (Rails 2.3.2)
>> Object.new.send!
NoMethodError: undefined method `send!' for #<Object:0x2378780>
