404    
405            * R/Matrix.R (Matrix): no longer use coercions to specific classes
406                    (since we are discouraging them in user code).

451            order to match the generic (and evade .local(..)).

476                    before we use as(., <Tsparse>)[...] anyway
477    
478            * R/Rsparse.R (.viaC.to.R): mostly instead of .viaC.to.dgR()
