* Make reference(_internal) the default return value policy for properties Before this, all `def_property*` functions used `automatic` as their default return value policy. This commit makes it so that: * Non-static properties use `reference_interal` by default, thus matching `def_readonly` and `def_readwrite`. * Static properties use `reference` by default, thus matching `def_readonly_static` and `def_readwrite_static`. In case `cpp_function` is passed to any `def_property*`, its policy will be used instead of any defaults. User-defined arguments in `extras` still have top priority and will override both the default policies and the ones from `cpp_function`. Resolves #436. * Almost always use return_value_policy::move for rvalues For functions which return rvalues or rvalue references, the only viable return value policies are `copy` and `move`. `reference(_internal)` and `take_ownership` would take the address of a temporary which is always an error. This commit prevents possible user errors by overriding the bad rvalue policies with `move`. Besides `move`, only `copy` is allowed, and only if it's explicitly selected by the user. This is also a necessary safety feature to support the new default return value policies for properties: `reference(_internal)`. |
