You are not the first person who ask this question. I will add control
to the Py++ over this
functionality. Now possible solution:
mbuilder = module_builder_t( ..., optimize_queries=True, .... )
#execute next code before any other statement.
#this is needed because you modify declarations tree.
#You can not change source code, but you do can change what Py++ sees
Foo = mbuilder.class_( "Foo" )
constructors = Foo.constructors()
for c in constructors:
if not c.is_copy_constructor:
Foo.remove_declaration( c )
mbuilder.run_query_optimizer()
This should help. If not, comeback and I will add "no_init"
functionality to the class.
