Detailed Description

A stack object to be created when performing template instantiation.

Construction of an object of type InstantiatingTemplate pushes the current instantiation onto the stack of active instantiations. If the size of this stack exceeds the maximum number of recursive template instantiations, construction produces an error and evaluates true.

Destruction of this object will pop the named instantiation off the stack.
