/* Some notes on Lua bindings for libardour and friends
 *
 * - Prefer factory methods over Contructors whenever possible.
 *   Don't expose the constructor method unless required.
 *
 *   e.g. Don't allow the script to construct a "Track" Object directly
 *   but do allow to create a "BBT_TIME" object.
 *
 * - Do not dereference Shared or Weak Pointers. Pass the pointer to Lua.
 * - Define Objects as boost:shared_ptr Object whenever possible.
 *
 *   Storing a boost::shared_ptr in a Lua-variable keeps the reference
 *   until that variable is set to 'nil'.
 *   (if the script were to keep a direct pointer to the object instance, the
 *   behaviour is undefined if the actual object goes away)
 *
 *   Methods of the actual class are indirectly exposed,
 *   boost::*_ptr get() and ::lock() is implicit when the class is exported
 *   as LuaBridge's "WSPtrClass".

	/* LuaBridge uses unique keys to identify classes/c-types.
	 *
	 * Those keys are "generated" by using the memory-address of a static
	 * variable, templated for every Class.
	 * (see libs/lua/LuaBridge/detail/ClassInfo.h)
	 *
	 * When linking the final executable there must be exactly one static
	 * function (static variable) for every templated class.
	 * This works fine on OSX and Linux...
	 *
	 * Windows (mingw and MSVC) however expand the template differently for libardour
	 * AND gtk2_ardour. We end up with two identical static functions
	 * at different addresses!!
	 *
	 * The Solution: have gtk2_ardour never include LuaBridge headers directly
	 * and always go via libardour function calls for classes that are registered
	 * in libardour. (calling lua itself is fine,  calling c-functions in the GUI
	 * which expand the template is not)
	 *
	 * (the actual cause: even static symbols in a .dll have no fixed address
	 * and are mapped when loading the dll. static functions in .exe do have a fixed
	 * address)
	 *
	 * libardour:
	 *  0000000000000000 I __imp__ZZN9luabridge9ClassInfoIN6ARDOUR7SessionEE11getClassKeyEvE5value
