i dunno about other applications, but in audio it wouldn't be unheard of to
have an FIR equalization filter (that likely starts out with a non-zero
impulse sample) followed by a delay to compensate for some other delay
disparity (say for time-alignment of staggered loudspeakers).

can't think of a radically different example.   :-/

Many thanks for all your replies.
