1013//
1014// Notes:
1015//
1016// 1. The arguments are passed by value by default. If you need to
1017// pass an argument by reference, wrap it inside ByRef(). For
1018// example,
1019//
1020// InvokeArgument<1>(5, string("Hello"), ByRef(foo))
1021//
1022// passes 5 and string("Hello") by value, and passes foo by
1023// reference.
1024//
1025// 2. If the callable takes an argument by reference but ByRef() is
1026// not used, it will receive the reference to a copy of the value,
1027// instead of the original value. For example, when the 0-th
1028// argument of the mock function takes a const string&, the action
1029//
1030// InvokeArgument<0>(string("Hello"))
1031//
1032// makes a copy of the temporary string("Hello") object and passes a
1033// reference of the copy, instead of the original temporary object,
1034// to the callable. This makes it easy for a user to define an
1035// InvokeArgument action from temporary values and have it performed
1036// later.
