This list is the right place to discuss adding new features, no need to
open an issue for that.

I agree, sounds useful. The question is in what function(s) exactly.
signal.correlate is the first one that comes to mind. numpy.correlate might
also make sense. We have two many of these functions (scipy.ndimage has yet
more convolve/correlate functionality), so I'm not sure.
