new constants have security problems

This is why `inspect` sometimes doesn't work. There are probably a lot of other problems it creates too.
Here is a tryruby session:
    >> 6.tainted?  
    => false  
    >> /slash/.tainted?  
    => false  
    >> TryRubyBaseSession.tainted?  
    => false  
    >> class MyClass; end  
    => nil  
    >> MyClass.tainted?  
    => true  
    >> MyClass.new.tainted?  
    => true  
    >>
