new
Answer a new method. It has no name yet, but will before it gets used in a send phrase. It gets named by virtue of it being referenced by one or more message bundless, each of which keeps track of how to parse it using that bundle's name. The bundles will be grouped into a bundle tree to allow parsing of many possible message sends in aggregate.
A method is always shared, but its set of owning bundles, its tuple of definitions, its cached privateTestingTree, its macro testing tree, and its set of dependents chunk indices can all be updated (while holding a lock).
Return
A new method with no name and no definitions.
Parameters
num
The number of arguments that this method expects.
