(({:"!".inspect})) とか (({:!.inspect})) の結果が1.9.3devと1.9.2 では異なるようです。

$ bin/ruby -v -e 'puts :!.inspect'
ruby 1.9.3dev (2011-08-01 revision 32798) [x86_64-darwin10.8.0]
:"!"
$ ruby -v -e 'puts :"!".inspect'
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.6.0]
:!
$ bin/ruby -v -e 'puts :!.inspect'

ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.6.0]

ちなみに 1.8.7 では以下の通り、前者は1.9.3devと同じ出力で、後者はSyntaxError となります。
$ ruby -v -e 'puts :"!".inspect'
ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-darwin10.6.0]

$ ruby -v -e 'puts :!.inspect'

puts :!.inspect
