 In the first call to \tcode{factory},
-\tcode{A1} is deduced as \tcode{int}, so 2 is forwarded
+\tcode{A1} is deduced as \tcode{int}, so \tcode{2} is forwarded
 to \tcode{A}'s constructor as an rvalue.
 In the second call to \tcode{factory},
 \tcode{A1} is deduced as \tcode{int\&}, so \tcode{i} is forwarded
 to \tcode{A}'s constructor as an lvalue. In
 both cases, \tcode{A2} is deduced as \tcode{double}, so
-1.414 is forwarded to \tcode{A}'s constructor as an rvalue.
+\tcode{1.414} is forwarded to \tcode{A}'s constructor as an rvalue.
