Perhaps we don't need the second sentence on the `msg` argument which isn't
adding anything new.
Ideally it should be more clear when the method operates in context manager
mode.
("If only" and "possibly" don't play nicely together.)
Maybe along the lines of "If no callable was passed as an argument ..." ? I
haven't looked in to the actual implementation yet...
