Thanks for the tip. OTOH, I wasn't talking about triangular_matrix in
particular. Are you implying that one has to revert to writing function wrappers
as above to infer the correct types? For example, is there a mechanism to get
the layout_type (row_major/column_major) from a matrix<> ?

Personally, when I want to dispatch to specific specializations, I us the tags
system (row_major_tag/column_major_tag), but some functions require the actual
layout_type class to be passed as an argument.
