Follow-up from "Default constructible geometries"
The following discussion from !224 (merged) should be addressed:
-
@santiago.ospina started a discussion: (+4 comments) [...] In the
test-multilineargeometry
this storage is defined as astd::reference_wrapper
that is not default constructible and so it not the whole multilinear geometry class. [...]This sounds like simple "view". I would write this as a raw pointer where
nullptr
means that is unassigned.
