There ir no way to retrive the names and values of the macros a Host will use.

In host.get, you have a selectMacros but will only retrive the macros defined at host level.

Of course we can retrieve the templates attached to the host, but the mechanism of determining the value of a macro will be hard, in case the macro is in more than one template or in the global level.

There is a inheritedTags parameter, a inheritedMacros will be nice. In this property will be all the macros with its values

Using macro.get, is the same thing. There is a inherited parameter but is for retrivig the inherited macros on a host prototype.
