Yes, i wondered why there was no compiletime version of this. I use it in several places, and which corner i want is always known at compile time. Does it really provide room for improvement to know this at compile time ?

Indeed, i very often do things like m.corner(TopLeft, m.rows(), smaller_nb_of_cols). Not a very big deal for me, but i could use some one-parameter stuff like Bottom/Top. I wouldn't like to prevent you working on more important features though!
