Metabang-Bind combines several of the different lexical binding techniques into one facility. The types of binds it currently supports are LET, DESTRUCTURING-BIND, MULTIPLE-VALUE-BIND, binding on property lists, binding to structure slots, binding to class slots (with the option of using accessors), and destructuring arrays. In addition, BIND is also extensible via CLOS, so you can introduce your own binding methods.

ArrayPad[array, m] gives an array with m 0s of padding on every side. ArrayPad[array, m, padding] uses the specified padding. ArrayPad[array, {m, n}, ...] pads with m elements at the beginning and n elements at the end. ArrayPad[array, {{m1, n1}, {m2, n2}, ...}, ...] pads with mi, ni elements at level i in array.
