Clear a terminal screen for real

Question

I know the solution employing printing of new lines isn't much supported, but if all else fails, why not? Especially where one is operating in an environment where someone else is likely to be able to see the screen, yet not able to keylog. One potential solution then, is the following alias:

alias c="printf '\r\n%.0s' {1..50}"

Then, to "clear" away the current contents of the screen (or rather, hide them), just type c+Enter at the terminal.
