yeah. but if thats not a concatenation or an addition the programmer of
the operator overload should be shot on sight.

hmm.. i dont really see the advantage of writing an engine in C.
first of all you loose RAII locks.

then you need to manage most memory yourself again....

could you explain your reasons a bit more ?

there is a reason why gob2 and vala emerged.
writing a GObject in C is a pretty big PITA.
its probably possible to create the boilerplate out of some kind of

but i am not aware of some rails/paster like framework to create this
boilerplate with a single command.
