+Feature: Operator Matchers
+
+ RSpec provides a number of matchers that are based on Ruby's built-in
+ operators. These mostly work like you expect. For example, each of these pass:
+
+ * 7.should == 7
+ * 25.2.should < 100
+ * 8.should > 7
+ * 17.should <= 17
+ * 3.should >= 2
+ * [1, 2, 3].should == [1, 2, 3]
+ * "this is a string".should =~ /^this/
+ * "this is a string".should_not =~ /^that/
+ * String.should === "this is a string"
+
+ RSpec also provides a `=~` matcher for arrays that disregards differences in
+ the ording between the actual and expected array. For example:
+
+ * [1, 2, 3].should =~ [2, 3, 1] # pass
+ * [:a, :c, :b].should =~ [:a, :c] # fail
