charset="utf-8" From: Markus Armbruster QAPISchemaGenCommandVisitor.visit_command() needs to generate the marshalling function into the current module, and also generate its registration into the ./init system module. The latter is done somewhat awkwardly: .__init__() creates a QAPIGenCCode that will not be written out, each .visit_command() adds its registration to it, and .visit_end() copies its contents into the ./init module it creates. Instead provide the means to temporarily switch to another module. Create the ./init module in .visit_begin(), and generate its initial part. Add registrations to it in .visit_command(). Finish it in .visit_end().
