ruby -v: ruby 1.9.3dev (2011-08-01 revision 32798) [x86_64-darwin10.8.0]

(({:"!".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 1.9.3dev (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]
 :!

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'
 ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-darwin10.6.0]
 -e:1: syntax error, unexpected '!', expecting tSTRING_CONTENT or tSTRING_DBEG or tSTRING_DVAR or tSTRING_END
 puts :!.inspect
        ^
