Yes, 

irb(main):010:0> 'testing' != /test/
irb(main):011:0*

Found this in a previous ruby-talk message:

        (Actually, a !~ b is the same as !(a =~ b), i.e. there is no !~
        method as
        such; in the same way that a += b is expanded to a = a + b and
        so there is
        no += operator as such)

So this expansion only works with a String on the rhs?
