Already exists:
warning: function ./length.m shadows a built-in function
It appears every time the function is added to the load path (e.g. when
Octave starts, when changing directories, calling addpath, or pkg load).
It is *not* called every time the shadowed function is called, that
would be very annoying.
And it is apparently not called when a new function or script file shows
up in a directory that is already on the load path. That might be worth
reporting as an enhancement.
