I would like to stick to standard bean behavior for properties.
If there is no () on the end then it is expected to be a property
as per the bean spec. I didn't really look a whole lot at WM :-)
But we can certainly add it if people want it that way.

It would be easy enough to add, yes.

$gunslinger.TriggerFinger would not translate
into $gunslinger.hasTriggerFinger() as per the bean spec.

The ASTIdentifier.init() figures out whether it's dealing
with a property or a Map. There is an AbstractExecutor, and
MapExecutor and PropertyExecutor subclasses. The executor is
store for the subsequent renderings. The Introspector is not
used in the ASTIdentifer (maybe it should be), but the results
of determining whether it's a Map or Property are stored for
future use.
