def handle_call(defined_class, hook_method, receiver, args)
  name, prefix, partial = args
  warn "Resolver: #{{ name: name, prefix: prefix, partial: partial }}" if LOG

  AppMap::Handler::Function.handle_call(defined_class, hook_method, receiver, args)
end

.handle_return(call_event_id, elapsed, return_value, exception) ⇒ Object

When the resolver returns, look to see if there is template rendering underway. If so, populate the template path. In all cases, add a TemplateMethod so that the template will be recorded in the classMap.
