[C++-sig] [Py++] Help with wrapping setter methods

[Christopher Bruns]

Please help.  I am just a beginner with pyplusplus and am not smart
enough to see how to create certain complex rules.

How would I create a pyplusplus rule for setting the return policy to
"return internal reference" for all member functions that meet the
following criteria:
  * method name begins with "set"
  * return type is a reference to the parent class or to one of its base classes

I would sincerely appreciate an example that could do this.  Then
perhaps I might be able to figure out how to perform other clever
manipulations.  Thanks in advance for your help.

struct Foo {
    // example of the sort of method I mean
    Foo& setBaz(int baz); // returns reference to self
};
#################################
from pyplusplus import module_builder
from pyplusplus.module_builder.call_policies import *
mb = module_builder(...)
# want "something" below...
mb.decls(<something?>).call_policies = return_internal_reference()
