------------------------+---------------------------------------------------
When building a new class (strong algebraic structure of parent) which
have a structure of module, one "can" only use CombinatorialFreeModule. It
will be very very good to do that with FreeModule (speed, use all
functionalities of FreeModule)
See that :
{{{
sage: class Bla_parent(sage.modules.free_module.FreeModule_generic):
....: class
Element(sage.modules.free_module_element.FreeModuleElement_generic_dense):
....: pass
....:
sage: F = Bla_parent(QQ,6,6)
sage: F
<class '__main__.Bla_parent_with_category'>
sage: p = F.Element(F,(1,2,3,4,5,6))
sage: p
(1, 2, 3, 4, 5, 6)
sage: p.__class__
<class '__main__.Element'>
sage: (p+p).__class__
<type 'sage.modules.free_module_element.FreeModuleElement_generic_dense'>
}}}
