+	// 					-> 'location:?'					- get the default for '*'
+	// 					-> 'location:*:save' (pre)
+	// 					-> 'location:file:save'			- forms the return value

+	// 		...the only thing this adds is a way not to call some of the 
+	// 		overloading actions via a simple pattern matching mechanism...

+	// 				.dispatch('location:file:save', ..)
+	// 					-> calls only the "save" actions that match the

+	// 		...for pure actions this is also possible by manually checking
+	// 		some condition and doing nothing if not matched...
