@orlando was asking me about the standard basis for finite free modules. All the std_basis machinery seems to be set up for arbitrary products (where the standard basis is not a basis). Where should he look for facts about the free RR-module RnR^n?

Is there nothing about this in linear_algebra/basis.lean?

There is stuff like equiv_fun_basis there Orlando -- is this enough for you?
