=~ is a String method.


--------------------------------------------------------------
String#=~
      str =~ obj   => fixnum or nil
------------------------------------------------------------------------
      Match---If _obj_ is a +Regexp+, use it as a pattern to match
      against _str_,and returns the position the match starts, or +nil+
      if there is no match. Otherwise, invokes _obj.=~_, passing _str_
      as an argument. The default +=~+ in +Object+ returns +false+.

         "cat o' 9 tails" =~ /\d/   #=> 7
         "cat o' 9 tails" =~ 9      #=> false
