Qt 5.0 released

While the libsigc++ and Booost style slot equivalents don't directly support introspection (they are just class members), you could layer that on top easily enough without needing an external tool to do so; though I'm not familiar enough with the internals of moc to know if that could be done compatibly or not WRT the signature extraction. You'd probably still need some preprocessor support to register and define the slot in a single statement.

Regarding the C++ dialect issues--I think we're talking at cross-purposes here; I don't think we're in disagreement, just misunderstanding.
